Impacting Pendulum Formula

  1. Apr 8, 2007 #1
    I need to run an experiment using a swinging steel ball pendulum to impact diffrent materials to determine impact integrity in g's.
    What is the formula for this? In g (x times gravity)

    There is no easy way to calculate g forces by that method because it depends on how much the sample deforms during the collision. Usually, such an apparatus is used to find fracture energy.
