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. 6-44).The strobe rate is
2000 flashes per second; the bolt has
mass 33 g and is at radius 4.0 cm.What is the magnitude of the force
on the bolt from the rod?
