Consider a lamina in the shape of a half annulus with inner radius 5 and outer radius 9. The mass density at any point is directly proportional to the distance to the origin. Compute the moment of inertia with respect to the diameter.

Don’t leave the proportionality constant in the answer. You may, however, leave m in your answer, so you may need to compute that as well. What does diameter mean for a half annulus? It means the same thing that it would be if it were a half disk.

Consider the hemispherical shell of inner radius 3 and outer radius 7. The mass density at any point P(x,y,z) is directly proportional to the square of the distance from P to the origin. Set up an integral in an appropriate coordinate system for the moment of inertia about the z-axis. Simplify your integrand as much as possible, but do not evaluate the integral.

A large wooden turntable in the shape of a flat uniform disk has a radius of 1.65 m and a total mass of 135 kg. The turntable is initially rotating at 3.10 rad/s about a vertical axis through its center. Suddenly, a 65.5-kg parachutist makes a soft landing on the turntable at a point near the outer edge. (a) Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle.)...
