What this mean is that the object in motion will move in the direction
of movement. But when there is a force that tries to change that
motion usually from the engine or transmission the pulley will move
when it's not intended to. Scroll down to Figure 4.2. It may explain
more about centrifugal force not centripetal force. Centripetal is
moving or directed toward a center or axis. The theory is that the
centrifugal force can effect the bolt's movement in some way or
just simply tighten up bolt.

That's a good description.
Could someone please explain what self-tightening and
self-locking bolts are and give examples. The author may
have the latter in mind.
"Figure 4.1 This picture explains the great inertia and
centrifugal force"
"When ever there is a difference in inertial force (as
pointed out with the arrows) the pulley will move. Not
180-ft-lb torque can hold the pulley still."
I wonder what this is about.
