Factors such as brake shoe orientation, pin location, and direction of rotation determine whether a particular brake shoe is considered to be self-energizing or self-deenergizing. Sketch a brake drum where the left shoe is self-energizing and the right shoe is self-deenergizing. Which shoe will produce more braking torque, assuming equal actuation forces and identical brake shoes

Answer:

Self energizing brake shoe produces more Torque

Explanation:

Attached below  is the sketches of the various cases

The cases are :

case 1 ; deenergizing

case 2 ; self energizing

case 3 ; produces high braking torque

For a brake to be self energizing when the Frictional torque and braking torque are in the same  direction

summary from equation 3

when:  b > uc  the brake is controllable

           b = uc  It is self locking

           b < uc  The brake is uncontrollable
