è la versione ampliata e aggiornata del corso di inglese tecnico settoriale rivolto agli studenti degli Istituti Tecnici Tecnologici, indirizzo Meccanica, meccatronica ed energia. In queste pagine troverai alcune indicazioni per imparare a usare il tuo libro di testo.
Il volume si articola in 9 moduli dal contenuto tecnico e settoriale e 4 dossier di civiltà, organizzati in questo modo:
Roles in engineering
Mechanical engineers and computer systems Mechanical engineers do much of their work on computers. They use them to design new tools, test a machine’s functions, ensure the quality of all devices. Computers systems as 2D and 3D Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) are employed for design-data processing and for turning the design into the final product. These programs allow engineers to create simulations of the operation of products, as well as the manufacturing process to be used. So their final performance is optimized before settling on a particular design.
WARM UP
1
Do you know which are the main branches of engineering?
Mechanical engineers
power-generating machines: macchine produttrici di elettricità turbines: turbine power-driven machines: macchine elettriche elevators: ascensori escalators: scale mobili
Mechanical engineering is the second-largest field of engineering. The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed as mechanical engineers are involved in the work on all stages of a product from research and design, to construction and testing. They work on various types of machines, tools, engines and thermal devices. Perhaps the one skill that is the mechanical engineer’s exclusive area is the ability to analyze and design objects and systems with motion.

simulations: simulazioni piping: tubature
Main tasks of mechanical engineers VIDEO
Since almost every industry relies on mechanical systems and devices, mechanical engineers play a central role in many companies. Their work varies by industry and function. They often work in testing laboratories, in checking the manufacturing of machinery. They work on power-generating machines such as electric generators, internal combustion engines, and steam and gas turbines. They also develop power-driven machines such as refrigeration and air conditioning systems, material handling systems, elevators and escalators, and robots used in the manufacturing process. They often work in offices, but sometimes they are asked to visit worksites to solve equipment problems.
Engineering is not a man’s world only: history has known a few women which contributed significantly to engineering. Helen Augusta Blanchard (1840-1922), with 28 patents, was one of the great inventors of the industrial era. Lillian Moller Gilbreth (1878-1972) was the first woman to be elected to the National Academy of Engineering (1977). Rear Admiral Dr. Grace Murray Hopper (19061992) first had the idea of the development of more user-friendly programming languages. Nancy D. Fitzroy (1927) was among the first engineers to work on nuclear reactor cores. Yvonne C. Brill (1924), a brilliant propulsion engineer, made satellites stay in orbit longer.
12
Mechanical engineers and their specialized fields Among the main specialized fields are mechatronics, energy systems, applied mechanics, automotive design, plant engineering and maintenance, pressure vessels and piping, heating and refrigeration. Besides, new job opportunities for mechanical engineers are created by many emerging innovations in biomechanics, energy conversion, laser-assisted materials processing, and nanotechnology.

WARM UP
Service sector
Listening
The tertiary sector is the largest in the UK and the economic output of the sector is worth 80% of all UK economic output. 86% of the workforce is employed by this sector which includes government, healthcare, financial services, banking, retail, education and tourism. The government, education, health and defence sector employs 7.6 million people, 27% of the total workforce. The retail and wholesale industry employs around 4.4 million people. The retail market has shown a slow, but gradual growth since the 2008 credit crunch decreased consumer spending. This market is dominated by large chain stores, which Britain’s Tesco is the world’s third credit crunch: stretta del operate in most sectors like largest retailer after America’s credito Walmart and France’s Carrefour. food, clothing and electrical goods. This means that smaller and independent shops find it more difficult to compete. For example, four supermarket chains – Asda, Tesco, Sainsbury’s and Morrisons – have over 75% of the market share. Most major stores also have online shops and the number of exclusive online retail businesses has grown rapidly over the last few years, following the sharp rise in internet shopping. Tourism is also a key part of the UK economy, with London being one of the top tourist city destinations in the world. It has been the fastest growing sector in the UK in terms of The Tower of London is one of London’s employment since 2010, and the tourism industry is predicted to most popular tourist attractions. be worth over £257 billion by 2025. Over 1 million people work in the financial services sector, and about one third are employed in London. Edinburgh, Leeds and the North West are also significant centres for the number of employees in financial services. The City of London is one of the leading international financial and banking centres in the world, with hundreds of foreign banks, offices and subsidiaries. It is home to the London Stock Exchange, the Bank of England and Lloyd’s – the world’s specialist insurance market. With London being such a significant international financial centre, the global financial crisis of 2008 hit the UK economy hard as banks had to make thousands of workers redundant and reduce their international operations. However, since then it has maintained The City of London a strong position within the global market and is predicted to or the ‘Square Mile’ continue to grow, thanks also to increased overseas investments.

Can you remember what percentage of the workforce is employed in the service sector in the UK? Why do you think it is so high? Has it always been this way?
Current UK economic situation At the end of 2008, the UK was in a serious recession as a result of the global crisis, with declining house prices and high consumer debt. In 2010, the government introduced a five-year austerity programme to lower the country’s level of debt, cutting public spending and services and increasing taxes. Between 2009 and 2010, the Bank of England injected £200 billion into the economy through quantitative easing in order to help the country climb out of the recession by increasing spending and economic growth. Towards the end of 2011 it added a further £75 billion due to growing fears connected to the eurozone crisis. Since 2013, the economy has grown, albeit sluggishly, every year with services increasing fairly strongly but manufacturing and construction showing a slight drop. Since early 2016 unemployment has been below 5%, and the employment rate is at a record high. After Brexit referendum the pound has fallen by about 10% against other currencies, rising the UK goods and services’ competitiveness. Quantitative easing is In 2017 inflation peaked at around 3%, as pound’s fall caused the price of import to a process by which a rise, but it will be Central Bank creates back down again soon, as exchange-rate effects fall out of the year-on-year comparison money and uses it to used to calculate it. Low inflation is a good thing: with nominal wages increasing at 2% buy assets such as a year, inflation should fall below 2% and real wages should rise again. government bonds and More, lower inflation means that the purchasing power is eroded less quickly. All high-quality debt from this suggests that private companies. the unanimity forecast for economic growth in 2018 – around 1.8% – is probably about right. The bigger risk, however, remains Brexit.

The British Imperial System is the traditional system of weights and measures used officially in the United Kingdom from 1824 until 1995, when the metric system was adopted in most cases. Back in the 19th century, the system was extended to all countries of the British Empire but nowadays most of these too have officially adopted the metric system as their main system of measurement. In the United Kingdom the Imperial System is still used in road signs (miles and yards instead of kilometres). Office space and industrial units are usually advertised in square feet. Although official figures always include litres per 100 km equivalents, fuel consumption for vehicles is commonly stated in miles per gallon.

What is engineering? In simple words we might say that engineering is the profession that puts power and materials to work for man. Engineers use steel and concrete to construct buildings, dams, roads, and bridges. They use metal, glass, plastics and many other materials to make hundreds of everyday products. They control the power of petrol and other fuels that drive our airplanes, trains, ships, and cars. They often discover or create new materials and sources of power that serve man. Engineering activities are carried out in a huge variety of industries. They are employed in car and aircraft industries, chemical industries, food manufacturers, clothing companies, electronics companies: almost every company that makes a product employs or uses the skills of engineers.

Main branches of engineering Engineering is a very large field. It is usually divided into four main branches (chemical, civil, electrical and mechanical engineering) which are, in turns, divided into many other specialized branches. So, there is a wide variety of jobs available in engineering. These range from practical roles, such as machine operators and fitters, to technical roles, such as designers and metallurgists, to line and factory management, to the directors who run the companies. As you can see there are many specialized fields, but the dividing line between some of them is not always clear. For example, aeronautical engineering involves some aspects of both civil and mechanical engineering.

Engineering as a subject to study We can easily affirm that engineering was born with man, in ancient times; inventions as simple as the wedge, lever, wheel and pulley were the very first, basic examples of a discipline whose study is as complex as fascinating. Thanks to engineering the Egyptians built the Pyramids, the Romans built bridges, aqueducts, and roads, the Chinese built the Great Wall, and so on; without engineers, our world would be a completely different place.

MORE ABOUT...
As an engineer student, your choice about which branch to study is quite endless: infrastructure and building; communications and satellites; electronics, computers and robotics; energy and petroleum, structures and materials, vehicles and aircraft, and many others. To master power and materials in order to produce things, from nails to skyscrapers, an engineer must know and use principles of science and mathematics, physics and chemistry; he has to study constantly to keep up with the newest engineering developments. So, the steps of production in which an engineer may be involved are: • designing products, through drawing, modelling, testing; • selecting the materials to be used; • planning production activities; • making products using a wide range of different equipment, ranging from hand tools, to machine tools, to automated equipment.
Mechatronics is a multidisciplinary branch of engineering combining mechanics, robotics and electronics where the principles of electrical, mechanical, computer and industrial engineering merge together to give birth to all complex modern devices. In Module 8 the topic will be dealt with exhaustively.

DID YOU KNOW…? Engineering is not a man’s world only: history has known a few women which contributed significantly to engineering. Helen Augusta Blanchard (1840-1922), with 28 patents, was one of the great inventors of the industrial era. Lillian Moller Gilbreth (1878-1972) was the first woman to be elected to the National Academy of Engineering (1977).
Engineering is a very broad study subject which divides into many different and highlyspecialised disciplines (civil, mechanical, chemical, environmental, electrical – just to name a few), so career choices are quite limitless. Engineering graduates develop a range of practical skills, such as logical thinking, numeracy and problem-solving, which are highly valued by employers in many sectors.
Mechanical engineers Mechanical engineering is the second-largest field of engineering. The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed as mechanical engineers are involved in the work on all stages of a product from research and design, to construction and testing. They work on various types of machines, tools, engines and thermal devices. Perhaps the one skill that is the mechanical engineer’s exclusive area is the ability to analyze and design objects and systems with motion.
Main tasks of mechanical engineers Since almost every industry relies on mechanical systems and devices, mechanical engineers play a central role in many companies. Their work varies by industry and function. They often work in testing laboratories, in checking the manufacturing of machinery. They work on power-generating machines such as electric generators, internal combustion engines, and steam and gas turbines. They also develop power-driven machines such as refrigeration and air conditioning systems, material handling systems, elevators and escalators, and robots used in the manufacturing process. They often work in offices, but sometimes they are asked to visit worksites to solve equipment problems. Mechanical engineers work in many industries as automotive, aerospace, computers and electronics just to mention a few.
Rear Admiral Dr. Grace Murray Hopper (19061992) first had the idea of the development of more user-friendly programming languages. Nancy D. Fitzroy (1927) was among the first engineers to work on nuclear reactor cores. Yvonne C. Brill (1924), a brilliant propulsion engineer, made satellites stay in orbit longer.

Mechanical engineers and computer systems Mechanical engineers do much of their work on computers. They use them to design new tools, test a machine’s functions, ensure the quality of all devices. Computers systems as 2D and 3D Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) are employed for design-data processing and for turning the design into the final product. These programs allow engineers to create simulations of the operation of products, as well as the manufacturing process to be used. So their final performance is optimized before settling on a particular design.
Mechanical engineers and their specialized fields Among the main specialized fields are mechatronics, energy systems, applied mechanics, automotive design, plant engineering and maintenance, pressure vessels and piping, heating and refrigeration. Besides, new job opportunities for mechanical engineers are created by many emerging innovations in biomechanics, energy conversion, laser-assisted materials processing, and nanotechnology.

Mechanics Mechanics are workers who keep the machines of modern life running smoothly and efficiently. These workers are related to various branches of mechanics. Some branches deal with fluids and gases while others work with disciplines connected to electricity. Vehicle mechanics are skilled in servicing and repairing cars and lorries. Their job tasks usually include inspecting the parts of a vehicle, evaluating its overall condition, diagnosing problems and making repairs. They also perform routine tune-ups and change the oil. A secondary school certification is the minimum educational qualification necessary to work as a mechanic. Positions require hands-on work as well as a working knowledge of computer technology. A mechanic should be fit in order to work in all sorts of positions: in, around and under the car and should have the hand strength to loosen and tighten nuts or bolts. They shouldn’t be afraid of a few scratches or scraped knuckles.

Professional welders
WARM UP
The job of a welder is complex and challenging. Sometimes welders will spend the day cutting, shaping, and combining materials to make different parts for a variety of industries. Some of these may include the construction, engineering, automobile, or aerospace fields. Whichever field is chosen, the tasks tend to be similar across the board. Welders select the materials to be joined or cut, arrange them in an appropriate configuration, then follow a specific design or blueprint to create the desired product. Sometimes a welder has to perform certain melting methods on materials such as lead bars to complete a project. Welders are also in charge of fixing structural repairs and making sure welding machinery and equipment is in order. Several different types of materials are used on a daily basis including composite material, alloys, or metals. Some welders who choose to follow a more specific route, work with complex laser or ultrasound welding equipment. A career in welding will sometimes require working with dangerous tools in high-risk environments. Getting into the habit of wearing the appropriate protective gear is an absolute necessity. Welders should be familiar with the latest welding tools and methods and should have the ability to stay focused at all times. It would also be helpful to have a vast amount of knowledge of different welding design techniques and equipment preferences. Welding also requires someone with a confident building and construction ability to ensure effective repair and equipment maintenance. A person with excellent construction skills usually has a very logical mind and excels in problem-solving situations. A well-rounded mathematical understanding is a valuable trait for welders to have. It isn’t necessarily a requirement for a job, but is attractive to employers who are looking for welders able to perform many different tasks on the job site.

Even though welders work in different fields, their tasks are similar. Welders do not use a variety of materials. Welders never work with dangerous tools. Knowledge of welding design techniques and a good mathematical understanding are useless skills.

Production stages: from product design to manufacturing Design and drawing feasibility: fattibilità prototype: prototipo forging: contraffatto layout: impostazione grinding: molatura melting: fusione casting: colata coating: rivestimento
The first stage of production, the initial planning, starts when customers send product plans and quality specifications to the manufacturer. After considering the feasibility of the proposed product on a commercial scale, a prototype is crafted. The process of product development, prototype production and prototype evaluation is repeated until the prototype reaches the standard of quality required. Then a forging simulation of the prototype production is carried out using 3D modelling software CAD (Computer Aided Design); in this way, problem areas which show the theoretical stresses and strains on the product can be easily highlighted. Commercial production begins based on the manufacturing design and layout proposed in the prototype production planning stage. At this stage engineers make improvements and modifications.
Manufacture
A CT IV IT IE S
The manufacturing process takes place in the machine shop. The manufacture of material products involves many unit processes that alter the external form and surface as well as the interior structure of the material components and final assembly. These include such processes as grinding, melting, chemical processing, casting, deformation processing, forming, machining, coating, and joining just to mention a few.

Jobs in the production stages Stage 1 The first people involved in the initial planning stage of production are designers or design teams. They study all the factors that may influence the product design and then produce the final design in the form of a layout. Then draftsmen/women draw a prototype. Their drawing represent general assembly as well as individual parts. Mechanical drawing is exacting work, and expert draftsmen are in great demand.
Stage 2 Craftsmen/women are those involved in the manufacturing process. They receive and interpret the prototype sent by designers and draftsmen. Besides knowing about computers, tools and machines, craftsmen have to know the basic rules of workplace safety: they work in a potentially dangerous place, so safety is of the main importance when handling tools and operating machines.
draftsman: disegnatore tecnico, progettista assembly: assemblaggio backdrop: sfondo layer: strato
MORE ABOUT... A craftsman/woman, by definition, is someone with great skill in his/her craft. But the essence of the word has changed with its changing context. Against the backdrop of mass-production, ‘craftsmanship’ carries the implied meaning of something made with special care, time and attention. A craftsman is someone who manufactures the product by hand, using dedicated human reasoning to make it a high-quality, functioning piece.

Safety first! WARM UP

The SAFE acronym stands for: a ■ Slow down Attention Fire Escape b ■ Stay Away Fire Extinguisher c ■ Spot the hazard Assess the risk Find a safer way Everyday
workplace: posto di lavoro hazards: pericoli slippery: scivolosi frayed: logorati

The importance of safety Safety in the workplace is the priority of companies towards their employees. Regardless the size or type of the business, workplace safety procedures are mandatory for all the workforce. Moreover, a safe work environment is a productive one: avoiding or minimizing damage to equipment and facilities as well as injuries to people will result in fewer expenses and more profit for a business. Companies that put safety first turn out higher quality products. By working in a clean, efficient and safe environment, workers are able to reduce distractions and truly focus on the quality of what they do. To be actually effective, a safety program must include hazard identification and control, risk analysis, safety education and appropriate practice policies.
Spot the Hazards Hazards are usually classified into health and safety hazards. Health hazards are those situations which may result in occupational illnesses: chemical, biological, physical agents; noisy machinery that could affect your hearing, etc. Safety hazard are those which result in physical injuries. Slippery floors, shifting materials, frayed electrical cords (could result in electrical shock); boxes stacked precariously (they could fall on someone). It’s important for workers to stay alert on workplace, checking for anything that may be dangerous. If they see, hear or smell anything odd, they must take note and, if they think it could be any kind of hazard, they must tell the safety manager.
MO DULE 1 | FOCUS ON THEORY
Assess the risk A risk is the chance a hazard may occur, causing specific harm or injury to people or damage to property. Assessing the risk means evaluating how likely it is that a hazard will harm someone and how serious the harm could be. Whenever a hazard is spotted, the risk must be assessed by asking how likely it is that the hazard could harm someone. When employees are unable themselves to fix hazards that could cause serious harm, it is crucial to ask supervisors or safety managers the safest way to do it. Employers are responsible for their companies’ safety policies but employees also play an important role in ensuring safety in the workplace. Their diligent compliance with the safety guidelines is essential in preventing accidents at work.
DID YOU KNOW…? Workers’ compensation is an insurance which pays monetary benefits to workers who become injured or disabled because of their employment. Depending on local legislation, it covers various job-related injuries, including death, due to an accident or occupational disease. It is a publicly-sponsored system; it provides compensation for economic loss (both past and future), reimbursement or payment of medical expenses, and benefits payable to the family of workers killed at work (functioning in this case as a form of life insurance). General damage (pain and suffering), and damages due to worker’s negligence are generally not included in compensation plans.

Safety education
WARM UP
It is your employer’s responsibility to fix hazards on workplace. Sometimes you may be able to fix simple hazards yourself, as long as you don’t put yourself or others at risk. For example, you can pick up things from the floor and put them away to eliminate a trip hazard. The best way to fix a hazard is to get rid of it. This is not always possible, but employers should try to make hazards less dangerous by looking at the following options (in order from most effective to least effective).
Elimination
Sometimes hazards – equipment, substances or work practices – can be avoided entirely; for example, cleaning high windows from the ground with an extendable pole cleaner, rather than by climbing a ladder and risking a fall.
Substitution That is, when a less hazardous thing, substance or work practice can be used, such as using a non-toxic product instead of a toxic one.
1
Name three of the legal duties of employers about safety.
get rid of: liberarsi di welding screens: schermi da saldatura forklifts: carrelli elevatori earmuffs: paraorecchie shutdown: chiusura emergency cut-out: interruttori di emergenza
Isolation Separate the hazard from people, by marking the hazardous area, fitting screens or putting up safety barriers: welding screens can be used to isolate welding operations from other workers; barriers and/or boundary lines can be used to separate areas where forklifts operate near pedestrians. Safeguards
can be added by modifying tools or equipment, or fitting guards to machinery. These must never be removed or disabled by workers using the equipment.
Instructing workers in the safest way to do something
This means developing and enforcing safe work procedures. Students on work experience must be given information and instruction and must follow agreed procedures to ensure their safety.
Using personal protective equipment and clothing (PPE)
If risks remain after the options have been tried, it may be necessary to use equipment such as safety glasses, gloves, helmets and earmuffs. PPE can protect you from hazards associated with jobs such as handling chemicals or working in a noisy environment.

MO DULE 1 | CLIL
Ergonomics (from the Greek ergon, work, and nomoi, natural laws) is the scientific study of people in their workplace. The goal of ergonomics is to reduce stress and eliminate injuries and disorders associated with the overuse of muscles, bad posture, and repetitive tasks. This is accomplished by designing tasks, work spaces, controls, displays, tools, lighting, and equipment to fit the employee’s physical capabilities and limitations. The first step for good ergonomics is the selection of furniture that can be easily adjusted to meet the needs of the different users and the design of objects that can be better adapted to the shape of the human body. Common examples include chairs designed to prevent the user from sitting in positions that can have detrimental effect on the spine, and ergonomic desks with adjustable keyboard trays, desktops of variable height and other elements which can be changed by the user. Establishing a good ergonomics process can help reduce the frequency of MSDs (musculoskeletal disorders), address ergonomic risk factors and concerns, and control workers compensation costs. To minimize the risk of MSDs a workstation should provide: • good workstation chairs • proper keyboard and mouse placement • correct monitor positioning • sufficient lighting to help reduce eyestrain. And to avoid MSDs you should: • change your work position, chair height and angle, and keyboard position throughout the day • look away from the screen periodically to focus on distant objects • use the “alt” functions on your keyboards where possible to reduce mouse use. • hold the phone with a non-writing hand or use a headset: do not hold the phone with your chin and shoulder as this can lead to neck tension, headaches and pinched nerves • stand to reach for items on shelves above the desk, rather than from the chair • squat or go to one knee while getting materials from bottom drawers or shelves. Some rest periods must also be planned. For instance, working at the computer should include breaks every two hours to protect the worker’s eye. Changing work habits can increase workers’ safety and comfort through education and workstation modifications, rather than making costly furniture or equipment purchases.
