moment
The turning effect of a force about a pivot.
pivot
The fixed point around which a lever rotates.
moment
The turning effect of a force, calculated as the product of the force and the perpendicular distance from the pivot.
pivot
The point about which a lever rotates, crucial for determining the moment produced by a force.
moment
The turning effect of a force, calculated as the product of the force and the perpendicular distance from the pivot.
perpendicular distance
The shortest distance from the line of action of the force to the pivot point, used in calculating the moment.
