problem 6 friction, two blocks connected with rigid link which is hinged at a point

Описание: Two blocks A and B weighing 1999 N each are connected by weightless link which is hinged at point O, subjected to horizontal force P required to keep the blocks from slipping as shown in diagram. Coefficient of friction is 0.25 for all contact surfaces . Find the applied force P to keep system in equilibrium position.
