Two discs A and B have same mass and same thickness but A is made of aluminium and B is made of lead. Which has larger moment of inertia about the central axis?

Text Solution

AI Generated Solution

To determine which disc has a larger moment of inertia about the central axis, we can follow these steps: ### Step 1: Understand the Moment of Inertia Formula The moment of inertia \( I \) for a solid disc about its central axis is given by the formula: \[ I = \frac{1}{2} m r^2 \] where \( m \) is the mass of the disc and \( r \) is its radius. ...
