Question 2178 Deck Safety
70% to passThe moment created by a force of 12,000 tons and a moment arm of 0.25 foot is _______________.
A
48,000 ft-tons
B
0 ft-tons
C
6,000 ft-tons
D
3,000 ft-tons
AI Explanation
The correct answer is D) 3,000 ft-tons. The moment created by a force is calculated by multiplying the force (in this case, 12,000 tons) by the moment arm (0.25 foot). The formula for calculating moment is: Moment = Force x Moment Arm. Plugging in the values, we get: Moment = 12,000 tons x 0.25 foot = 3,000 ft-tons. The other answer choices are incorrect because: A) 48,000 ft-tons is too high, as it does not match the calculation. B) 0 ft-tons is incorrect, as the moment is not zero. C) 6,000 ft-tons is too high, as it does not match the calculation.
