Question: A bolt is threaded onto one end of a thin horizontal rod, and the rod is then rotated horizontally about its other end. An engineer

A bolt is threaded onto one end of a thin horizontal rod, and the rod is then rotated horizontally about its other end. An engineer monitors the motion by flashing a strobe lamp onto the rod and bolt, adjusting the strobe rate until the bolt appears to be in the same eight places during each full rotation of the rod (Fig. 6-46).The strobe rate is 2000 flashes per second; the bolt has mass 30g and is at radius 3.5cm. What is the magnitude of the force on the bolt from therod? Bolt Rod Strobed positions
