Ballista

I made this Ballista as a school project and thought it would be a cool thing to enter. It uses the elasticity in the rope to launch the dowling forward.

oh and how far does it shoot?

[tylerpienta]

its not the elasticity of the rope its the torsion power when you twist it one way really tight it wants to unwind the opposite way and when you wedge a piece of wood or pipe in between the strands and twist it even more the opposite way when you draw it back it springs forward launching your projectile

How many times did wrap the rope

How long were the arms on the ballista compared to the size of the frame that held the arms?
