Question

A physical pendulum consists of a uniform rod of length L = 1.5 meters

A physical pendulum consists of a uniform rod of length L = 1.5 meters. The mass of the rod is 5kg and the rod is pivoted about its end. The rod is pulled out to an angle of è0=0.2rad and is then given a push so that its instantaneous angular velocity is -0.5 rad/sec.
a) What is the period of the oscillator?
b) Determine the function for è(t), the angular displacement from vertical as a function of time.
c) What is the angular kinetic energy of the rod after 1.0 sec?
d) What is the maximum torque on the rod during the course of its oscillation?
