A soda bottle cap wobbles when spinning. Assume that the cap is a thin disk of radius R and a mass M attached to a cylinder of height R, radius R, and mass M, as illustrated below R-height-radius Derive the moment of inertia tensor I around the bottle cap's center of mass. As measured relative to its own center of mass, the MOI for a disk around the principal axis perpendicular to the plane of the disk (ê3) is 1/2MR2,...

A uniform disk has a mass of 3.7 kg and a radius of 0.40 m. The disk is mounted on frictionless bearings and is used as a turntable. The turntable is initially rotating at 30 rpm. A thin - walled hollow cylinder has the same mass and radius as the disk. It is released from rest, just above the turntable, and on the same vertical axis. The hollow cylinder slips on the turntable for 0.20 s until it acquires the...

A pendulum consists of a disk of mass, m, and radius, r, connected to a pivot point via string (of negligible mass) of length, l. Note, the disk hangs vertically and the string is attached to its top. For small angles, derive an expression for: (a) angular position as a function of time (b) angular velocity as a function of time (c) angular acceleration as a function of time
