moment of force
Physics term for the rotational effect of a force; equivalent to torque. Used in technical contexts.
力の能率は、力の大きさと支点からの距離の積で表される。
The moment of force is expressed as the product of the magnitude of the force and the distance from the pivot.
Compound of 力 (force) + の (possessive particle) + 能率 (efficiency, rate). The combination specifically translates the physics concept 'moment of force'.
