In the following diagram, the mass of block A is Q kg and the mass of block B is 1000 kg. A single cable, which runs horizontally between each block and the wall, goes around two frictionless pulleys at the wall. The plane where B and C meet is horizontal and P is a horizontal force. Coefficient of Static Friction HSAB=0.4 HSBC 0.3 Coefficient of Kinetic Friction MKAB=0.25 HkBC=0.2 A 30° B C a) Draw the free body diagrams of Block A and Block B. b) Determine the force of P that must be exceeded to raise block A (impending motion case) and the tension in the cable.
