If mass as well as the radius of gyration of the body are doubled, then its moment of inertia becomes :

A

two times

B

four times

C

six times

D

eight times

Text Solution

Verified by Experts

The correct Answer is:
D
`I = Mk^2"when"M=2M, k. = 2k`
`I.=2m (2k)^2 = 8Mk^2=81impliesI.81`.

Given the moment of inertia of a disc of mass M and radius R about any of its diameters to be MR^2//4 , find its moment of inertia about an axis normal to the disc and passing through a point on its edge.

Prove the result that the velocity v of translation of a rolling body (like a ring, disc, cylinder or sphere) at the bottom of an inclined plane of a height h is given by v^2=(2gh)/(1+k^2//R^2) using dynamical consideration (i.e. by consideration of forces and torques). Note k is the radius of gyration of the body about its symmetry axis, and R is the radius of the body. The body starts from rest at the top of the plane.
