- 1. Find the expression for the moment of inertia of a uniform, solid disk of mass M and radius R, rotated about an axis that goes through its center as shown in the diagram below. Hint: the moment of inertia of a thin ring is given by MR2. Divide the disk into a series of rings of radius r, mass dm, and thickness dr, then integrate over the rings. Your expression should only depend on the variables M and R. 99+I NEED HELP WITH BOTH QUESTION1. Find the moment of the 500 N force shown about Point A. Write your answer using 2 significant digits.

The diagram below indicates four different combinations of (1) net force on the rod, Fnet, and (2) net torque on the rod about its center of mass, Tnet. In each box, draw vectors that represent one or two forces that achieve the given combination of net force and net torque. If any combination is not possible, state so explicitly. looge ad For example: In the second case, indicate one or two forces that could be exerted on the rod so- that at the instant shown the net force on it is zero, but the net torque on it is not zero.
