Transcribed Image Text:A rotating shaft with a belt-type brake is shown
The static coefficient of friction between the
brake drum and the brake belt is 0.20. When a 75-lb force
P is applied to the brake arm, rotation of the shaft is pre-
vented. Determine the maximum torque that can be re-
in Fig.
sisted by the brake
If the shaft is tending to rotate counterclockwise.
