a thin wire of length l and mass m is bent in the form of semicircle. what will be the moment of inertia about an axis perpendicular to its plane and passing through the end of wire?

The length of the rod= Length of the semicircle= L= πR => R=L/πmoment of inetia of the circle about its free ends is the same as the moment of inertia of a circular ring of same parameters= mR²= mL²/2π²
