1: Truss design.
You must submit a valid design to me before you will receive your building materials. I will not grade your design based on whether it will support the necessary load. I am only approving it as to whether it is a design that meets the building requirements and is something you can analyze with the tools we have learned in this class.
Your design should be an approximately to-scale drawing of the truss that you will build with all dimensions and angles indicated. The location of cross pieces to connect the two trusses should also be indicated. Any modifications you make to the truss you plan to build must be approved before construction.
This is an all or nothing grade (i.e. a 0 or a 5) and is worth 10% of the total project grade.
2: Truss design equations
You must submit a complete set of equations evaluating the loads in each member of your truss before you will receive your building materials. I will not be checking each and every equation in great detail. I will only spot check them to make sure they seem reasonable and are complete. I will be checking to ensure that no loads exceed the maximum loads that balsa wood can hold - i.e. that the design meets the building code.
You should perform you're analysis as a function of applied load. Then when you are done, calculate the load in each member assuming the minimum required load. You must turn in the table at the end of this packet with your equations and again with your report. You should clearly indicate which members are in tension and which members are in compression. Estimate the maximum load that your truss will hold. If you make any modifications to the truss, you will need to modify your equations and recalculate the resulting member loads.
This is an all or nothing grade (i.e. a 0 or a 5) and is worth 30% of the total project grade.
Each time I find problems with your equations and give them back to you to correct. your wade will be decremented. Both team members must review the equations before turning them in.
