A standard clothes hanger makes a pretty good equal arm balance. With nothing on it, the hanger hangs free with the bottom side horizontal.    (A) while hanging normally, where is the axis of rotation for this equal arm balance located? With respect to the axis, where is the center mass located?    (B) if you tip the hanger with your finger then release it, it swings back and forth until friction stops it in a horizontal position. Use the concept of torque to explain why the hanger starts to swing when you release it.
