two circular loops P and Q are made

A uniform disc of mass M and radius R is mounted on an axle supported in frictionless bearings. A light cord is wrapped around the rim of the disc and a steady downward pull T is exerted on the cord. The angular acceleration of the disc is From a given sample of uniform wire P [...]

A disc of radius R rolls on a horizontal ground with linear acceleration a and angular acceleration α as shown in Fig. The magnitude of acceleration of point P as shown in the figure at an instant when its linear velocity is v and angular velocity is ω will be a From a given sample [...]

An isosceles triangular piece is cut a square plate of side l. The piece is one-fourth of the square and mass of the remaining plate is M. The moment of inertia of the plate about an axis passing through O and perpendicular to its plane is From a given sample of uniform wire P of [...]

Two circular discs A and B of equal masses and thicknesses. But are made of metals with densities dAanddB(dA>dB). If their moments of inertia about an axis passing through the centre and normal to the circular faces be IA and IB, then. From a given sample of uniform wire P of radius r and Q [...]

From a given sample of uniform wire, two circular loops P and Q are made, P of radius r and Q of radius nr. If the M.I. of Q about its axis is four times that of P about its axis (assuming the wire to be of diameter much smaller than either radius), the value [...]
