For the given figure, the brake can sustain a torque of 350 N-m and coefficient of friction between the band and drum is 0.3, find necessary force required for clockwise rotation of the drum in N.
(a) 32
(b) 64
(c) 96
(d) 128
The question was posed to me during an interview for a job.
This interesting question is from Differential Band Brake topic in section Brakes and Dynamometers of Machine Dynamics
