Catapult MA help

  1. Apr 22, 2013 #1
    Our class was tasked with building a catapult.
    We built ours based on DaVinci's
    We have a wheel and axle MA of 8 and a lever MA of 0.108
    We used a crank to stretch the cords, is this a machine that should be calculated in?

    Could you perhaps show us a sketch of your device, and be a bit more specific in the question that you are asking? Thanks. :smile:
