InterviewSolution

1.	The moment of inertia of a solid cylindrer about its axis of ratation is `(MR^(2))/(2)`. What is the value if the radius of gyration of the cylinder about this axis ?
Answer» `I=(MR^(2))/(2)`……..`(i)` `I=MK^(2)`…….`(ii)` Comparing `(i)`, `(ii)` `K^(2)=(R^(2))/(2)`, `K=(R )/(sqrt(2))m`
