Maths Engineering

Maths Engineering This Challenge must be read in conjunction with the 2011 Instruction Manual.


INTRODUCTION An unexpected change in climate has meant that the last pocket of rainforest that is home to the giant species, the Wairness, is under threat. One of the last of these giant species has fallen and a rescue needs to be mounted. Your team has been asked to raise this giant species and, in keeping with the International Year of Forests you are going to use only plant materials to build a device that will raise it.


CHALLENGE Your team must create a crane made only from paper and a plant starch-based glue, such as Clag paste. The total mass of the crane must be no more than 100g and it must be able to support as large a weight as possible from a part of the crane that extends 15cm beyond the edge of its base.


PRESENTATION During your presentation your team must: x Present the crane to the judges to confirm that it is less than 100g x Inform the judges and audience of the weight of each new load prior to hanging it from the crane x Explain the importance of the Wairness x Explain how your actions will help the sustainable management of the world’s forests. During your demonstration x The crane must support the load you provide when it is hung at least 15 cm out from the table (see diagram on last page of this Challenge). Any number of attempts using the same or different loads can be made within the ten minutes, provided each load is announced before testing. Before you commence your presentation you must present the following written information to the judges: x One copy of your script x Your completed copies of the Cost Form, Outside Assistance Form and Presentation Skills Form. x A diagram explaining the design elements of your crane and giving the weights of the crane and all loads.

LIMITATIONS Refer also to those listed in the 2011 Instruction Manual.



The total time for setting up, performing the Challenge solution and clearing away is ten minutes.


The judges or room monitor will indicate when your performance time is to begin and when nine minutes have elapsed. At ten minutes your performance will be stopped.


A minimum of four team members must be within the performance area at all times.


The team members who are performing must be visibly inside the 3m x 3m performance area.


Only items listed under ‘Allowable Materials’ may be used for costumes and props.


Overall costs are limited to $75.00 in accordance with the 2011 Instruction Manual


The crane must only be made out of 80gsm A4 photocopy paper (of any brand or colour) and a plant starch-based glue such as Clag paste. (The paper may be cut to shape.)


The team must also make the loads and means of attachment to the crane out of (any) plant materials. (The attachment materials e.g. cotton thread, can be included as part of the load.)


The crane must not be touched or supported, except while a new load is attached, when it is being demonstrated that the crane can support a particular load.


The weight of the load may be counter-balanced by placing wooden blocks on any part of the crane provided the blocks do not extend over the edge of the table, do not rest directly on the table and are not part of the crane structure.


The crane must not be attached or glued to the table or held down in any way except by the wooden blocks.


Use of materials other than those allowed (or outside the cost limit), or other failure to meet all the requirements, will mean that the maximum load suspended will be zero.


If you present digital images you must provide your own computer, projector and screen.

SCORING You will be awarded points according to the following criteria. 1.

The creativity and originality of the explanation of the importance of the Wairness......... 20 points


The creativity and originality of the explanation of how your actions will help the sustainable management of the world’s forests............................................ 20 points


The maximum load suspended as a fraction of 1kg times 60........................................... 60 points


Ingenuity, creativity and elegance of the construction, including the loads and means of attachment, particularly as set out in your explanatory diagram................ 50 points


In addition, the teams with the cranes which carried the 1st, 2nd & 3rd heaviest loads at each Tournament (in each Division) will receive 20, 10 & 5 additional points.............. 20 points Maximum possible ......................170 points

However, we ask that before a team member does this, that they do two things: (1) carefully check this Challenge document and the 2011 Schools’ Instruction Manual, as most often the answer is included in one or both of these documents; and (2) consult the Team Facilitator, who should also refer to the Challenge, the 2011 Schools’ Instruction Manual and log in to the TOM Portal to check the responses to other general clarifications that have already been answered.
