Two charged objects are connected to a spring with force constant k = 500 N/m and unstretched length L_0 = 50 cm. The magnitude of each charge is the same. The charge on the left is fixed to the wall, but the charge on the right is free to move on the frictionless surface (stretching or compressing the spring) until it reaches equilibrium. If the objects are 1.0 m at equilibrium, what is the magnitude of each charge? 167 mu...

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...
