Question

point masses m1 and m2 are placed at the opposite ends of a rigid rod of length L and negligible mass. The rod is to be set in rotation about an axis perpendicular to it. Find the position on this rod through which the axis should pass in order that the work required to set the rod in rotation with angular speed omega should be minimu
