resistance force : ウィキペディア英語版 | resistance force
In physics, resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pounds-force. For an ideal (frictionless) mechanism in which no energy is lost, resistance force obeys the relation: : where: :''R'' equals resistance force :''DR'' equals resistance distance :''E'' equals effort force :''DE'' equals effort distance Resistance force is used to calculate the work output using the following equation: :
