Prove that the M.I. of a uniform Disc about an axis perpendicular to in plane and passing through centre of mass is`frac( 1)(2) MR^2`

The square lamina of side 'b' has same mass as a disc of radius R. The M.I. of the two about an axis perpendicular to the plane and passing through the centre are equal. The ratio b/R is

If the moment of inertia of a thin uniform circular disc about diameter „is I, then its M.I. about an axis perpendicular to its plane and passing through a point on its rim will be

In a Faraday disc dynamo, a metal disc of radius R rotates with an angular velocity about an axis perpendicular to the plane of the disc and passing through its centre.The disc is placed in a magnetic field B acting perpendicular to the plane of the disc.Determine the induced emf between the rim and the axis of the disc.

The moment of inertia of a circular ring about an axis passing through is diameter is I. This ring is cut then unfolded into a uniform straight rod. The moment of inertia of the rod about an axis perpendicular to its length passing through one of its ends is

A thin uniform rod 2m long has a mass of 0.6 kg. Find its moment of inertia and radius of gyration about an axis perpendicular to its length and passing through: its centre

A uniform circular disc of radius 50 cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of 2 rad s^(-1) . Its net acceleration in ms^(-2) at the end of 2 s is approximately
