Question
Which of the following is the correct expression for determining the moment of inertia of a hollow cylinder?
Correct Answer
Option A is the correct answer.
Detailed Explanation
For a hollow cylinder (thick-walled) rotating about its axis, the moment of inertia is ½m(R₁² + R₂²), where R₁ and R₂ are inner and outer radii.
Hint
Moment of inertia depends on mass distribution.
