Question 4562 Deck General

The correct answer is D) It decreases. When retrieving wire rope using a winch, the pulling power of the winch decreases due to the increased friction between the wire rope and the winch drum. As the wire rope is wound onto the drum, the diameter of the drum increases, which reduces the mechanical advantage of the winch. This causes the pulling power or line pull of the winch to decrease, even though the motor's torque may remain the same. The other options are incorrect because A) the pulling power does not remain the same, B) the fluctuation is due to the increasing drum diameter, not the gearing system, and C) the pulling power actually decreases, not increases, as the wire rope is retrieved.
