Question:
The moment of inertia of a solid circular cylinder of radius \( a \) and height \( h \) about its axis is:
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
Hide Solution
Verified By Collegedunia
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 \( a \).
