Problem P. 4517. (February 2013)
P. 4517. Four similar rods of uniform density are connected with frictionless hinges, and this frame is placed to a horizontal smooth tabletop, such that its shape is a square. Vertex P is acted upon by a horizontal force in the direction of the diagonal, and due to this force it begins to move at an acceleration of aP. What is the acceleration of the opposite vertex Q at which it begins to move?
