Week 2 Journal Patrick McDonald #636215 In our tutorial session this week we discussed several points, including columns & beams, frames, and mass construction. Mass constructed is categorized in two ways, small module and large module. Small module generally tends to deal with compression, or lateral, tensile forces. They have a recurring pattern and shape, which means that labor is often intensive costs money, and has a very slow production. Large module construction is generally quick, economically efficient, and has a good quality factor. An example could be precast concrete. We also explored columns and beams and what they are generally constructed from. They can either consist of base metals or alloys. Steel for example is made up of carbon and iron. Cantilevers were also explored in the tutorial, being either a fixed joint, which then relies on the stiffness on the beam and the ability of the column to counteract the moment force created by the weight of the beams and its load. This could be fixed by employing a backspan making it a lot stronger.


This week in our tutorial we learnt how to create strong towers that would be able to reach a great height using balsa wood and coming up with a concept of how to support our vertical columns. First we brainstormed our ideas and thought of different truss structures and then work out the strongest solution to create our tower. We decided to use a triangular structure, as this is the strongest geometric shape to use. As our tower grew to bigger heights we had to make it stronger by making the joints between the pieces of balsa wood stronger. We used both super glue and sticky tape to achieve this. To strengthen our tower structurally we connected truss supports around the tower that changed their direction of slope each level. This compensated for any tension or compression forces on the tower as more weight was added to the bottom of the structure.
