A solid disc is recast into a thin walled cylinder of same radus. Which will have larger moment of inertia ?

An iron disc and a wooden disc have the same radius. Then which will have larger moment of inertia about the diameter ?

A ring and a circular disc of different materials have equal masses and equal radii. Which one will have a larger moment of inertia about an axis passing through its centre of mass perpendicular to its plane ?

Two discs A and B have same mass and same thickness but A is made of aluminium and B is made of lead. Which has larger moment of inertia about the central axis?

There is a solid sphere of mass m. Moment of inertia about the axis passing through the centre of sphere is I. If the material of the sphere is recast to a disc of same radius then what would be its moment of inertia?

A disc of metal is melted and recast in the from of a soild sphere. What will happen to the moment of inertia anout a vertical axis passing through the centre ?

Assertion (A) Two circular discs of equal mass and thickness made of different materials, will have same moment of inertia about their central axes of rotation. Reason (R) Moment of inertia depends upon the distribution of mass in the body.

A solid metallic cone is melted and recast into a solid cylinder of the same base as that of the cone. If the height of the cylinder is 7 cm, the height of the cone was

A solid sphere of mass M and radius R having tmoment of inertia I about its diameter is recast into a solid dise of radius r and thickness t. The moment of inertia of the disc about an axis passing the edge and perpendicular to the plane remains I. Then R and r are related as

The inner and outer radii of a hollow cylinder are 15 cm and 20 cm, respectively. The cylinder is melted and recast into a solid cylinder of the same height. Find the radius of the base of new cylinder.
