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

AThe brake is electrically set and spring released, and the brake automatically releases when power is removed from the electric drive motor.
BThe brake is spring set and electrically released, and the brake automatically releases when electric power is removed from the electric drive motor.
CThe brake is spring set and electrically released, and the brake automatically sets when electric power is removed from the electric drive motor.
DThe brake is electrically set and spring released, and the brake automatically sets when electric power is removed from the electric drive motor.
AI Explanation

The correct answer is C) The brake is spring set and electrically released, and the brake automatically sets when electric power is removed from the electric drive motor. This is correct because the automatic electric brake on a capstan is designed to be in the set position when no electric power is applied. When power is supplied to the electric drive motor, the brake is then electrically released to allow the capstan to rotate. If the power is removed, such as in a loss of power scenario, the brake will automatically set due to the spring-loaded design, stopping the capstan. The other options are incorrect because they describe the opposite behavior - a brake that automatically releases when power is removed, rather than automatically setting in that situation.
