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.

A disk initially at rest is fixed to a vertical axis of rotation and a 40 kg child is standing on the disk initially at rest 0.5 meters away from the axis of rotation. The rotational inertia of the disk is 50 kgm2. The boy pushes and jumps off the disk and the disk begins to rotate at 0.5 rad/s. Calculate the velocity of the child as they push off the disk.

A rod of length 0.50 m and mass 4.0 kg rotates in a horizontal plane about and axis through its center. The rod is at rest when a 3.0 g bullet traveling in the rotational plane is fired into one end of the rod. As viewed from above the bullet's path makes an angle of 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 10 rad/s immediately after the collision, determine the before collision velocity of the bullet. Use conservation of angular momentum. The initial momentum is the point mass momentum of the bullet (the rod is originally at rest). Don't forget to include the bullet when you determine the after collision rotational inertia of the system.
A lawnmower blade has a length of 0.75 m and a mass of 1.5 kg. The blade rotates around its center at an rev angular velocity of 500. The end of the blade hits a 0.25 kg croquet ball (point mass), and the ball sticks to min the blade. Before the collision, the ball was stationary. After the collision, the ball will be moving at the same angular velocity as the blade at a distance of half of the blade length from the axis of rotation. Treat the blade as a rod rotating around its center. The final moment of inertia of the lawnmower blade and croquet ball combo is kgm2.
