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

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

The correct answer is D) 0.02 foot. To calculate the moment arm, we can use the formula: Moment = Force x Moment Arm. Rearranging this formula, we get: Moment Arm = Moment / Force. Given information: - Moment = 300 ft-tons - Force = 15,000 tons Plugging these values into the formula, we get: Moment Arm = 300 ft-tons / 15,000 tons = 0.02 foot The other answer choices are incorrect because: A) 25.00 feet is too large for the given moment and force. B) 0.04 foot is too large for the given moment and force. C) 50.00 feet is too large for the given moment and force.
