70% to passThe rudder torque capacity of the four ram steering gear illustrated is rated at 44,210,000 inch-pounds with one power unit in operation. If the four ram system was able to be operated as a two ram system with both power units on line, what would be the available torque? Illustration GS-0067
A11,052,500 inch-pounds
B22,105,000 inch-pounds
C44,210,000 inch-pounds
D88,420,000 inch-pounds
AI Explanation
The correct answer is B) 22,105,000 inch-pounds. The rationale is that with a four ram steering gear system, the torque capacity is rated at 44,210,000 inch-pounds with one power unit in operation. If the system is operated as a two ram system with both power units online, the available torque would be half of the original four ram system, which is 44,210,000 / 2 = 22,105,000 inch-pounds. The other options are incorrect because: A) 11,052,500 inch-pounds is only half of the correct answer. C) 44,210,000 inch-pounds is the rating for the four ram system, not the two ram system. D) 88,420,000 inch-pounds is double the correct answer and would not be the available torque for a two ram system.
