2.032 DYNAMICS Fall 2004 Problem Set No. 3 Out: Wednesday, September 29, 2004 Due: Wednesday, October 6, 2004 at the beginning of class Problem 1 A pendulum consists of a rod of length L with a frictionless pivot at one end. The pendulum is suspended from a . ywheel of radius R which rotates with . xed angular velocity ω , as shown below. (a) Determine the angular velocity of the rod in terms of ω and the generalized coordinate θ indicated in the sketch. (b) Calculate the velocity of the mid point C of the rod. Courtesy of Prof. T.
