A moment of 300 ft-tons is created by a force of 15,000 tons. What is the moment arm?

A 50.00 feet
B 25.00 feet
C 0.04 foot
D 0.02 foot
AI Explanation

The correct answer is D) 0.02 foot. To calculate the moment arm, we can use the formula for moment: Moment = Force x Moment Arm. Given that the moment is 300 ft-tons and the force is 15,000 tons, we can solve for the moment arm. Moment = 300 ft-tons Force = 15,000 tons Moment Arm = Moment / Force = 300 ft-tons / 15,000 tons = 0.02 foot The other options are incorrect because they do not correctly calculate the moment arm based on the provided information. Option A (50.00 feet) and Option B (25.00 feet) are too large, and Option C (0.04 foot) is too large as well.
