Question

The type of brake in which frictional force assists in applying the brakes is termed as

• A. Partially self-energising
• B. Self-locking
• C. Self-backing
• D. Self-acting

Hint:

Self-energising brakes use the frictional forces to aid the application while self-locking brakes prevent reverse motion Self-acting brakes do not require external force but rely solely on the frictional effect

Answer 1

The Correct Option is A

A partially self-energising brake utilizes the frictional force to assist in applying the brake which reduces the force needed by the operator This mechanism is commonly used in drum brakes where the friction increases the braking force as the brake shoes move
