Answer to Question #284699 in Mechanical Engineering for Aishwarya

Question

If the coefficient of friction is 0.3 and Contact angle is 850, determine the transmitted

breaking torque for the following shoe brake.

Answer 1

breaking torque $T_b = F_t \times r$

 $T_b = \mu N \times r$

$T_b = 0.3 N \times r$

Breaking Torque:

Brake torque is essentially the power of the braking system. The brake caliper acts on the disc at a certain distance from the hub center, known as the effective radius. The force exerted by the caliper, multiplied by the effective radius of the system equals the brake torque.
