Calculate the  rotational inertia of a meter stick, with mass 0.56 kg about an axis perpendicular to the stick and located at the 20 cm mark.  Enter units as kgm^2.  Hint:  Calculate the rotational inertia around the center of mass treating it as a thin rod and use the parallel axis theorem.

The uniform solid block in the figure has mass 47.6 kg and edge lengths a = 0.782 m, b = 1.61 m, and c = 0.108 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation axis Number Units

This problem illustrates the two contributions to the kinetic energy of an extended object: rotational kinetic energy and translational kinetic energy. You are to find the total kinetic energy Ktotal total of a dumbbell of mass m when it is rotating with angular speed ω and its center of mass is moving translationally with speed v. (Figure 1)Denote the dumbbell's moment of inertia about its center of mass by Icm. Note that if you approximate the spheres as point masses of mass m/2 each located a distance r from the center and ignore the moment of inertia of the connecting rod, then the moment of inertia of the dumbbell is given by Icm=mr2, but this fact will not be necessary for this problem.  Find the total kinetic energy Ktot of the dumbbell. Express your answer in terms of m, v, Icm, and ω.

Two wheels A and B in the figure are connected by a belt that does not slip. The radius of B is 6.03 times the radius of A. What would be the ratio of the rotational inertias IA/IB if the two wheels had (a) the same angular momentum and (b) the same rotational kinetic energy?
