A) Estimate the rotational inertia of a 60-kg ice skater by considering her body to be a cylinder. Assume she's holding her arms tight to her torso, so they don't contribute significantly to her rotational inertia. Suppose that the distance from the center of rotation to the shoulders is 0.2 mm.

B) Estimate the rotational inertia if she extends her arms fully. Suppose that the arm span of the ice skater is 1.6 mm and the arms make up 15 percent of skater's mass.

True/False: A machine’s efficiency can be over 100%. The rotational inertia of a body increases when the distance of its mass from the rotation axis increases. The Leaning Tower of Pisa is in stable equilibrium. When a tin can is whirled in a horizontal circle, the net force on it acts inward. You are in a car going over a cliff. You are weightless.

A cylinder with rotational inertia I1 = 2.6 kg · m^2 rotates clockwise about a vertical axis through its center with angular speed ω1 = 5.8 rad/s. A second cylinder with rotational inertia I2 = 1.3 kg · m2 rotates counterclockwise about the same axis with angular speed ω2 = 6.6 rad/s. If the cylinders couple so they have the same rotational axis, what is the angular speed of the combination (in rad/s)? What percentage of the original kinetic energy...

A 45 kg figure skater is spinning on the toes of her skates at 1.0 rev/s . Her arms are outstretched as far as they will go. In this orientation, the skater can be modeled as a cylindrical torso (40 kg , 20 cm average diameter, 160 cm tall) plus two rod-like arms (2.5 kg each, 69 cm long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to...
