Task id12742
A thread is wound around a hollow cylinder, the end of which is fixed to a stack at the top point of the inclined plane so that when the cylinder slides, the thread is always parallel to the inclined plane (Fig. 55). Determine the speed va of the cylinder at the end of a plane inclined to the horizon at an angle a = 60°, if at an inclination p = 30° it is equal to vb. The length of the inclined plane in both cases is equal to L.
