Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

they can slide without friction along the rod. They are initially held by
catches at positions 0.0550 m on each side of the center of the rod,
and the system is rotating at 48.0 rev/min. With no other changes in
the system, the catches are released, and the rings slide outward
along the rod and fly off at the ends.

A block of mass mmm = 1.7 kg is attached to a string that is wrapped around the circumference of a wheel of radius RRR = 8.7 cm . The wheel rotates freely about its axis and the string wraps around its circumference without slipping. Initially the wheel rotates with an angular speed ωω, causing the block to rise with a linear speed v = 0.33 m/s. Find the moment of inertia of the wheel if the block rises to a height of h = 7.6 cm before momentarily coming to rest.
A block of m = 2.00 kg hangs from a string that passes over a pulley with a moment of inertia / (to be determined) and a radius R = 0.44 m. The system of block and pulley is released from rest when the block is 5.00 m above the floor. It takes t = 1.17 s for the block to reach the floor. As the block accelerates downward, the pulley undergoes a counterclockwise angular acceleration. Using Newton's Laws (for linear and rotational motion), determine the moment of inertia I of the pulley.
