Trebuchet Part 3

Next Assignment: Trebuchet Part 4

Step 3b: Prototype'. Using the laser cutter in E1-135 (or the Idea Shop), fabricate your design. You may complete this portion of the project individually or with one other student. No groups of three are allowed. Both students must have completed the previous assignment. You may simply choose one design out of the two.
I will not accept any designs that use tape, wire, or string to hold parts together, even if the design works. We are engineers, not hackers!
