22 in 2. The object, which is very similar to the impact pendulum we will discuss, consists of an 8-lb, 22 inch slender bar welded to a 12-lb disk. It is released from rest in the horizontal position 1. Using a computer program, plot the force in the pin at A as a function of θ fro θ= 0 to 90, Partial answer: at θ= 450, A= 37.73 lbs, CM is 20.6 inches from A (you must prove this). 5 in
