Question 2183 Deck Safety

The correct answer is A) 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 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 options are incorrect because: B) 0 ft-tons would be the moment if the force or moment arm was 0, which is not the case here. C) 48,000 ft-tons is incorrect as it does not match the calculation. D) 6,000 ft-tons is incorrect as it does not match the calculation.
