A uniform disk with mass M = 0.24 kg and radius R = 0.15 m is free to rotate about the axis through its center. The disk stays static at the beginning. Then it experienced two constant forces, F, = 4.0 N has an angle 0 = 30° and F, = 3.0 N along tangential direction as shown in figure 1. Find (a) the rotational inertia of the disk. (b) magnitude of the torque caused by F. (c) magnitude of the torque caused by F2.

An old grindstone, used for sharpening tools, is a solid cylindrical wheel that can rotate about its central axle with negligible friction. The radius of the wheel is 0.330 m. A constant tangential force of 200 N applied to its edge causes the wheel to have an angular acceleration of 0.960 rad/s2. (a) What is the moment of inertia of the wheel (in kg · m2)? b) What is the mass (in kg) of the wheel?   (c) The wheel starts from rest and the tangential force remains constant over a time period of 4.50 s. What is the angular speed (in rad/s) of the wheel at the end of this time period?

The uniform solid block in the figure has mass 33.9 kg and edge lengths a = 0.618 m, b = 1.79 m, and c = 0.0701 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation axis Number Units
