problem 6-109 a rack and pinion system is sketched in figure P6-109. The axis of the pinion is fixed in frictionless bearings, and the flexible inextensible massless cord wrapped around the circular pulley of radius a is pulled by an external force f(t), which remains horizontal at all times.

Problem 6-62: In the system sketched in Figure P6-62, the cart has mass m and slides without fric- tion on the horizontal surface. A uniform cylinder of mass m and radius r is on the cart. The cylinder rolls without slip on the cart and is elastically restrained by the spring having spring constant k. The cart is acted upon by a horizontal force fi(t). The position of the system can be fully described by the two inertial displacements, xi(t)...
