A 81-lb sheet of plywood rests on two small wooden blocks as shown. It is allowed to lean 20° from the vertical under the action of a
force P which is perpendicular to the sheet. Friction at all surfaces of blocks A and B is sufficient to prevent slipping. Determine the
magnitude P and the vertical reaction forces at A and B.

Four identical rods, each of length = 1.3 m and weight 90 N, are connected at the frictionless pins A, B, C, and D. A compression spring of spring constant K = 5.3 N/mm connects pins B and C. and a weight W2 of 450 N is supported at pin D. The system is released from a configuration where = 45°. If the spring is not compressed at that configuration, show that the maximum de- flection of the weight We is 0.1966 m.
The flat band that goes from pulley A to pulley B has a
coefficient of static friction us=0.4, it prevents the motor
and its supporting weight of W=240 lb from falling.
Determine the moment that the belt transmits to pulley B
knowing that pulley A rotates clockwise.
