Question

The moment of inertia of a thin rod of mass m and length l about an axis perpendicular to the rod at its midpoint is Ml2​/2.
​a)What is the radius of gyration in the above case?
b) A student has to find the moment of inertia of the above rod about an axis (AB) perpendicular to the rod and passing through one end of the rod. Name and state the law used in this case.
c) Using the theorem, find the moment of inertia of the rod about AB.
