This curriculum was written and shared by Sean Mc Geough, Engineering Academy Instructor at Warren County Technical High School. Mr. Mc Geough and his class build a small scale trebuchet in 2009 and this year the class is building one on a larger scale. To give you an idea, last year the trebuchet was made out of 2x4s and the axle was made out of metal round stock.
This year the trebuchet is much bigger. They are using 4x4 posts as the base and metal round stock for axel. They also purchased a winch to pull back the weight. Those are all the secrets we are going to share here, but Mr. Mc Geough has offered his email mcgeoughs @ warrennet.org should you have questions.
