Two physical pendulums (not simple pendulums) are made from meter sticks that are suspended from the ceiling at one end. The sticks are uniform and are identical in all respects, except that one is made of wood (mass=0.39 kg) and the other of metal (mass=0.72 kg) They are set into oscillation and execute simple harmonic motion. Determine the period of (a) the wood pendulum and (b) the metal pendulum
From definition
and Torque
The moment of inertial of the rod about one end is
The time period of the rod about one end is
And since the length is same for both the lens, the time period also same, the time period is independent on mass of the rods.

just question 3a 3b Simple harmonic motion: pendulums Equipment Pendulum bobs String and support Meter stick & mass balance Photogate & Smart Timer Preliminary question 1. Describe simple harmonic motion in your own words. 2. Describe how mechanical energy is conserved during a pendulum's swing. 3. You have a 30.0 g pendulum bob attached to a string that is 50.0 cm long. You raise the bob so that the string makes a 20.0° angle with the vertical (as shown) and...
Two simple pendulums of equal length l = 0.35 m are suspended from the same pivot. The first bob is drawn back to make a 25° angle with the vertical, while the other one is initially hanging at rest. The first bob is released and allowed to elastically collide with the second bob. If the first bob has a mass of 0.20 kg and the second has a mass of 0.3 kg, how high will the second bob rise above...

Pendulum A is a physical pendulum made from a thin, rigid, and uniform rod whose length is d. One end of this rod is attached to the ceiling by a frictionless hinge, so the rod is free to swing back and forth. Pendulum B is a simple pendulum whose length is also d. Obtain the ratio TA/TB of their periods for small-angle oscillations.
