A differential band brake is used to retard a shaft carrying flywheel weighing 3 kN with radius of gyration 350 mm. If the brake drum diameter is 250 mm and coefficient of friction is 0.15, determine the following: (i) the braking torque when an effort of 150 N is applied at the end of the lever, (ii) number of revolutions of the flywheel before it comes to rest, and (iii) time taken by the flywheel to come to rest. The drum rotates at 500 rpm in clockwise direction and the layout of the brake is as shown in figure.

Question

A differential band brake is used to retard a shaft carrying flywheel weighing 3 kN with radius of gyration
350 mm. If the brake drum diameter is 250 mm and coefficient of friction is 0.15, determine the
following: (i) the braking torque when an effort of 150 N is applied at the end of the lever, (ii) number of
revolutions of the flywheel before it comes to rest, and (iii) time taken by the flywheel to come to rest.
The drum rotates at 500 rpm in clockwise direction and the layout of the brake is as shown in figure.
