A toothed wheel whose teeth engage the links of a chain.

Two different sized circular objects that are attached together and turn as one.

The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance form the point to the line of action from the force.

The amount of effort is takes to turn a force when the effort is applied parallel to the resistance and directly in the line of action neglecting the effect of friction.

Impeding effect exerted by one material object on another.

Work is the amount of force applied regardless of the distance the object moves.

Work is calculated as the product of force and distance only when an object moves in a perpendicular direction to the force.

Work is equal to the force applied on the object times the distance moved by the object in the direction of the force.

Work is the measure of energy transferred to an object when the object remains stationary.
