A 7.00-kg block is attached to a vertical rod by two strings, each of which has a length of 1.30-m, and attached to the center of the block’s face closest to the vertical rod. The strings are attached 2.25-m apart on the vertical rod, and the system rotates about the axis of the vertical rod. Sketch a real world picture of this scenario. Show how to determine the rpm at which the lower string goes slack. Show how to determine...

PROBLEM 2 Knee Extension - The angular motion of the lower leg about the knee joint, and the forces and torques produced by the muscles crossing the knee joint during knee flexions and extensions have been investigated by a number of researchers utilizing different experimental techniques. One of these techniques is discussed here. Consider the person illustrated in Fig. 10.12. The test subject is sitting on a table, with the back placed against a back rest and the lower legs...
