As it pertains to the automatic electric brake of a capstan, what statement is true?

Correct Answer: Option C — The brake is spring set and electrically released, and the brake automatically sets when electric power is removed from the electric drive motor.

Capstan brakes are designed as spring-set, electrically-released units to ensure safety during power loss. When the motor is energized, an electromagnet overcomes the spring force to release the brake. If power is removed, the springs immediately force the brake to set, locking the capstan and preventing load slippage.
