I ran across this problem studying for my exam, and I'm not sure how to solve it: 1. The problem statement, all variables and given/known data A thin rod of Mass M and length L is supported by a pivot a distance of L/4 from its left end. A second support a distance 3L/4 from the left end prevents it from falling. A clay ball of mass M/2 drops from a height H above the beam, strikes the left end and completely sticks to the rod. The beam swings upward to make an angle [tex]\Theta[/tex] with the horizontal. a. Calculate the moment of Inertia, Iz, of the beam and clay ball together around the pivot point, after the clay sticks to the beam. b. Calculate the angle [tex]\Theta[/tex] to which the beam rises. Express your answer in terms of [tex]\omega[/tex], V, and/or Iz. 3. The attempt at a solution For a, I was thinking of finding the moment of Inertia at the new center of mass after the ball sticks, then using the parallel axis theorem to get Iz, but that seems too messy.. For b, I think there must be some way to do it with energy conservation, but I really don't know where to start. Thanks for the help.
