A thin-walled, hollow spherical shell of mass m and radius r starts from rest and rolls without slipping down the track shown in the figure (Figure 1) . Points A and Bare on a circular part of the track having radius R. The diameter of the shell is very small compared to h0 and R, and rolling friction is negligible. a) What is the minimum height h0 for which this shell will make a complete loop-the-loop on the circular part of the track? b) How hard does the track push on the shell at point B, which is at the same level as the center of the circle? c) Suppose that the track had no friction and the shell was released from the same height h0 you found in part (a). Would it make a complete loop-the-loop? d) In part (c), how hard does the track push on the shell at point A, the top of the circle? e) How hard did the track push on the shell at point A in part (a)?

A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner...

A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner wall of a larger thin-walled hollow cylinder with mass m2 and radius R2 >> R1. Both cylinders' axes are aligned and horizontal, and some magical mechanism ensures this perfect friction contact between them. Unfortunately for you, the larger cylinder rolls without slipping on a horizontal surface. Describe the motion including small oscillation frequencies near any equilibria if the systems is released from rest with...

Show that the moment of inertia of a spherical shell of radius R and mass M about an axis through its centre is 2/3 MR2. Show also that the moment of inertia of a uniform solid sphere of radius R and mass M is 2/5MR2. The spheres are allowed to roll (from rest), without slipping a distance L down a plane inclined at a angle θ to the horizontal. Find expressions for the speeds of the spheres at the bottom...

a uniform spherical shell of mass M and radius R rotates about a vertical axis on frictionless bearing. A massless cord passes around the equator of the shell, over a pulley of rotational inertia I and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object after it has fallen a distance h from rest?...
