100lb truss
I can design and build a truss that can hold and withstand 100lB of force being applied on the top of it.
design constraints
there were a few things we had to follow while designing our trusses.
1.) The truss must be able to hold up 100lbs.
2.) We must use 1/8' material.
3.) A laminated piece must only be made up of no more than 2 pieces.
4.) Has to be at least 7' long, so it can fit into the tester.
5.) Can be no more than 4-1/2' tall.

brainstorming
there were many ideas that came to mind when i was brainstorming. However, only a few had calculated the actuall numbers i needed to hold the weight. I found out how much it would take before it broke by using formulas and then double checking them on a program on the computer. Most of the ones that had calculated out right, were so complicated and would have been so complicated to build. Its all about simple trusses that can hold the amount of weight needed. there was one that looked way simpler than the others, so i went with it.
computer model of truss
This is the final design of my truss. it met all of the design constraints givel. All that was left to do was print it out and build it. then finally test it. Mr. Wemp had set the truss tester to stop applying preasure at 100Lb's. so if your truss didnt break by the time it got to 100, then it passed.
RESULTS
In the end i didn't get to test my trust because i wasn't able to finish building mine before Mr. Wemp threw all the trusses away so we could move on to a new project. i don't think mine would have held up anyways. but it would have been cool to see it get crushed.
