**Small blocks, each with mass m, are clamped at the ends and at the center of a rod of length L and negligible mass**

Compute the moment of inertia of the system about an axis perpendicular to the rod and passing through a point one-fourth of the length from one end.

Express your answer in terms of the given quantities.

Since I=1/2mL^2 for a system about an axis perpendicular to the rod and passing through the center of the rod, can't I just add 1/4mL^2 + 1/2mL^2 and get 3/4mL^2=I for the equation?
