Question

KE13. 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 si of the body 1. The mechanism starts motion from rest, and at the beginning of the motion the spring is unstretched. During the motion the constant moment of resistance M is acting F on the pulley 3. Find the angular velocity ws of the pulley 4 at the instant when s1 0.2 m. Parameters: Rs 0.3 m, 0.1 m, and radius of gyration p 0.2 m, R 0.2 m, m 0 kg, m2 5 kg, ms 0 kg, m = 5 kg, m5 = 4 kg, c = 300 N/m, M- 1.5 Nm, F-85(5 + 6s) N. 45°
