Question

M.O.I. of a cylinder around its generator is

• A. $MR^2$
• B. $\frac {3}{2} MR^2$
• C. $2MR^2$
• D. $\frac {MR^2} {2}$

Answer 1

Answer: (B)

$\frac {3}{2} MR^2$

Answer 2

$I_{11} = I_{CM} + MR^2 = \frac{1}{2} MR^2 + MR^2 = \frac{3}{2} MR^2$ Generator of a cylinder is the axis tangential to surface of cylinder and parallel to main axis of the cylinder
