Which term describes the product of an item's weight and its distance from the datum?

Explanation:
The turning effect produced when a weight acts at a distance from a pivot is called a moment. This moment is calculated by multiplying the force (weight) by the perpendicular distance from the pivot (the moment arm). So, weight × distance gives the moment, which determines how strongly the object tends to rotate about the datum. The distance alone isn’t the effect, and the weight alone isn’t the effect; the product of the two is the moment. The term arm refers to that distance used in the calculation, not the rotational effect itself. For example, a 20 N weight at 0.3 m from the pivot creates a moment of 6 N·m, driving rotation.
