KE7. Figure shows a mechanism. Body 5 is assumed to be homogeneous circular cylinder, and mass of the pulley 4 is uniformly distributed over its rim. The coefficient of sliding friction between bodies and the plane is f 0.1. The coefficient of stiffness of a spring is c. A force F applied to the mechanism depends on the displacement s of the body 1. The mechanism starts motion from rest, and F at the beginning of the motion the spring...

edge is forced into a saw cut to prevent binding of the circular saw. The coefficient of static friction between the wedge and the wood is 0.25. Knowing that a horizontal force P with a magnitude of 30 lb was required to insert the wedge, determine the magnitude of the forces exerted on the board by the wedge after insertion. Fig. P8.58 7.5°
