Задача id12668

Two loads with masses m1 and m2 (m1 > m2) are connected by a thread thrown over a light block of radius r, the axis of which is horizontal. On the same axis with the block, four thin spokes of length l are fixed along the radii, at the ends of which small heavy balls of mass m are fixed (Fig. 36). The system comes into accelerated motion without an initial speed. Find the acceleration of the loads m1 and m2, assuming that there is no friction in the axis of the block, the thread does not slip over the block and the masses of the thread, block and knitting needles can be neglected.
