The moment of inertia of a cylinder of mass m, radius a, length l, about its axis is given by 3ma2/5. This cylinder is rolling with speed V on a rough horizontal plane and the coefficient of friction between the cylinder and the plane is u. A constant braking couple of magnitude 11umag/5 is applied to the cylinder at time t= 0 and is maintained. Show that the cylinder skids immediately. Show also that the cylinder will instantaneously cease to rotate at time V/2ug while still moving forward and calculate its forward speed at this instant.

A circular annulus, of mass M, inside radius a and outside radius 2a, is given an angular speed w about an axis, through its center perpendicular to its plane, which is horizontal. It is then gently placed on a rough horizontal plane, the coefficient of friction being u. Show that the annulus will start rolling without slipping after a time (10aw/13ug). The experiment is repeated in a space craft on a circular orbit around the earth. State giving reasons, whether...

1977M2. A uniform cylinder of mass M, and radius R is initially at rest on a rough horizontal surface. The moment of inertia of a cylinder about its axis is ½MR. A string, which is wrapped around the cylinder, is pulled upwards with a force T whose magnitude is 0.0Mg and whose direction is maintained vertically upward at all times. In consequence, the cylinder both accelerates horizontally and slips. The coefficient of kinetic friction is 0.5 On the diagram below,...

The moment of inertia of the human body about an axis through
its center of mass is important in the application of biomechanics
to sports such as diving and gymnastics. We can measure the body's
moment of inertia in a particular position while a person remains
in that position on a horizontal turntable, with the bodys center
of mass on the turntable's rotational axis. The turntable with the
person on it is then accelerated from rest by a torque that...
