Trebuchet Project

Trebuchet Project Overview
Objective - Create a trebuchet that launches a projectile to hit targets at specific distances, as well as launching the projectile the farthest distance.

Some criteria and constraints to think about:
Launched from the ground hands free for safety and stability reasons.
Calibrated to launch your projectile distances of 20 ft, 30 ft, and 50 ft.
Use a variety of materials (bought or found) but do not use a pre-made kit.
Trebuchet base must not exceed the area of 10 ft2.
There is a limited amount of materials in the classroom that you may freely use, however be sure to use them wisely.
Trebuchet will need to be painted.

Reviews will be given in the following areas:
Construction - How well was it built? Is it sturdy, level, square, etc.? Did you get poked, cut, jabbed, or need a tetanus shot after using it? Was it wobbly? Does it fall over?
Durability - How well will it withstand multiple usage? Did parts loosen, fall off, or break during use? Will it need to be maintained or repaired often?
Functionality - How easily can it be operated, moved, and/or placed in storage? Is it reliable, precise, and/or accurate?
Appearance - How well does it look? It is pleasing to the eyes, symmetrical, proportional? Are the lines and sides crisp, even, straight? How is the paint job?
Enjoyment of the Trebuchet- How well did you like using this trebuchet? If you acquired this free of charge, would you keep it or throw it out? Was this something that you would like to buy or build yourself?
A report must be given using the Engineering Design Process Rubric Guidelines. Use these guidelines as a means to generate your report.
