Question:

The moment of inertia of a solid circular cylinder of radius \( a \) and height \( h \) about its axis is:

Show Hint

Moment of inertia depends on the mass distribution relative to the axis of rotation.
Updated On: Mar 26, 2025
  • Independent of \( a \)
  • Independent of \( h \)
  • Independent of both \( a \) and \( h \)
  • Independent of its mass

The Correct Option is B

Solution and Explanation

The moment of inertia about the cylinder's axis is: \[ I = \frac{1}{2} M a^2 \] which does not depend on \( h \), only on the radius \( a \).
