PHY 101 Mechanical Equilibrium and Rotational Dynamics Objective Question
Take CBT

Question

A thin rod of mass m and length l has a moment of inertia given by (1/12)ml². This formula is valid when the axis of rotation is located where?
Options
A At one end of the rod
B At the centre of the rod
Correct Answer
C At a point one-quarter of the length from one end
D At any point along the rod
Correct Answer

Option B is the correct answer.

Detailed Explanation

The provided list of formulas specifies that the moment of inertia I = (1/12)ml² is for a thin rod with its axis of rotation passing through its centre, perpendicular to its length.

Hint

The formula for a rod's moment of inertia depends on where the axis of rotation is located.
