A light rod of length l1 is hinged to the surface of the earth, initially located vertically. At the upper end of the rod there is a load of mass m1, and at a distance l2 from the lower end there is a load m2 (Fig. 33). With what speed will mass m1 touch the ground if the bar starts falling without an initial speed? The mass of the rod can be neglected compared to the mass of the loads.
