Torsional Pendulum

A simple pendulum , a physical pendulum, a torsional pendulum and a spring-mass systeam, each of same frequency are taken to the Moon. If frequencies are measured on the moon, which systeam of systeams will have it unchanged?

STATEMENT-1 : Time period of a physical pendulumis independent of mass of the body. STATEMENT-2 : Time period ofa torsional pendulum is 2pi sqrt((l)/(k)) where, l= moment of inertia and k= Torsional constant. STATEMENT-3 : S.H.M. is an example of non-uniform motion.

The moment of inertia of the disc used in a torsional pendulum about the suspension wire is 0.2kg-m^2 . It oscillates with a period of 2s. Asnother disc is placed over the first one and time period of the system becomes 2.5s. Find the moment of inertia of the second disc about the wire.

An engineer has odd-shaped 10 kg object needs to find its rotational inertia about an axis through its center of mass. The object is supported on a wire stretched along the desired axis. The wire has a torsion constant k = 0.50 N.m . If this torsion pendulum oscillates through 20 cycles in 50 s, what is the rotational inertia ("in" 10^(-2) kg m^(2)) of the object?
