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.

2. An invention is designed to rotate a 2 kg camera/sensor setup on a 1.5-meter arm,
about a central 9 kg motor. We can neglect the mass of the 1.5-meter arm. The system
is resting on an icy lake (i.e. frictionless). When the arm rotates through one-half turn,
i.e. so that the 2 kg "ball" is to the left of the motor in the image shown, we see that the
9 kg motor has moved. As seen by a nearby observer, how far did it move, and in what
direction (left or right)?

4. A pottery wheel of radius 20cm and mass M is freely rotating about an axis through its center at 87 rads/s. A blob of very dense clay of mass 5kg is gently placed on the spinning wheel halfway up its radius (i.e. 10cm from the axis of rotation). This causes the rate of rotation of the pottery wheel to drop to 7.8a rads/s. You can treat the pottery wheel as a uniform disk and the blob of clay as a point particle. The moment of inertia of a disk about an axis through its center is given by I = MR. (a) Write down expressions for the angular momentum of the system before and after the blob has been placed on the wheel. (b) Hence, find the mass M of the pottery wheel.
