Homework Help: Energy absorbed using Charpy Test

  1. Sep 18, 2011 #1
    1. The problem statement, all variables and given/known data

    What would be the energy absorbed if a 60-lb, 31.5-in pendelum was released from an angle of 50 degrees hit a test bar, then rose to an angle of 20 degrees after impact?

    This is done using a Charpy Test

    2. Relevant equations

    Look at this problem in terms of change in potential energy, PE1 at initial release, PE2 at maximum height after impact.
