Question 111General Subjects - 1st Asst/Chief
70% to passAs it pertains to the automatic electric brake of a horizontal electro-mechanical anchor windlass, what statement is true?
AThe brake is spring set and electrically released, and the brake automatically sets when electric power is removed from the electric drive motor.
BThe brake is electrically set and spring released, and the brake automatically sets when electric power is removed from the electric drive motor.
CThe brake is electrically set and spring released, and the brake automatically releases when power is removed from the electric drive motor.
DThe brake is spring set and electrically released, and the brake automatically releases when electric power is removed from the electric drive motor.
AI Explanation
The correct answer is A. The automatic electric brake of a horizontal electro-mechanical anchor windlass is spring set and electrically released. This means that the brake is in the engaged or "set" position by default, using spring force. When electric power is supplied to the electric drive motor, the brake is then electrically released, allowing the windlass to operate. When electric power is removed from the motor, the brake automatically sets due to the spring force, stopping the anchor from unwinding. The other options are incorrect because they describe different brake configurations that do not match the characteristics of an automatic electric brake on a windlass system.
