An item weighs 200 pounds and sits at an arm of 60 inches. What is its moment?
Choices
260 inch-pounds
Moment is weight times arm, not weight plus arm.
3.33 inch-pounds
That divides weight by arm, which is not how moment is found.
✓ 12,000 inch-poundscorrect
Moment equals weight times arm: 200 x 60 = 12,000 inch-pounds.
120 inch-pounds
This is not the product of weight and arm.
Why
A moment is weight multiplied by arm. 200 pounds x 60 inches = 12,000 inch-pounds.
