A uniform thin rod of length 0.80m and mass 2.0kg is to be rotated about an axis perpendicular to the rod and passing through a point 0.20m from its centre.
a. (i) Derive an expression for the moment of inertia I of a uniform rod of length L and mass M about an axis perpendicular to the rod and passing through a point at a distance a from its midpoint.
b. (ii) Using the expression obtained in part (i), calculate the numerical value of I for the given rod.
