The coefficient of friction between the cylinder and the brake is 0.3. If the force P applied the brake is 20 N and the length d = 1.0 m, and a brake BC is to be arranged so that the speed of the cylinder may be reduced from 60 rpm to zero in 4 sec. Figure A is a solid cylinder weighing 600 N with a diameter of 0.60m. Find the total length L of BC. In m, 1 metric ton = 1,000kg = 9806.65 N THIRST |d=1.0 B 777 L-1 m a mm U
