Moment of normal force and frictional forces about the pivot axis are 640000N-mm and 250000N-mm respectively. If force acts at a distance of 190mm from the pivoted point, calculate the actuating force.
(a) 1078.6N
(b) 2052.6N
(c) 3223.5N
(d) 4454.5N
I was tested on this in my study session.
This question is from the Internal Expanding Brake topic in Friction Clutches, Brakes, Belt Drives and Chain Drives of Machine Design
