Mechanical advantage (MA)

Mechanical advantage is the ratio of the weight of a load to the effort used to lift or move the load. A high mechanical advantage indicates that a small effort is used to lift or move a large load. This value also shows how much the machine has simplified the work.

Units: Mechanical advantage has no units, since the unit of load is the same as the unit of effort.

Formula: MA = Load/Effort

Velocity ratio (VR)

Velocity ratio is the ratio of the distance moved by the effort to the distance moved by the load when doing work with pulleys.

Formula: VR = Distance moved by effort/Distance moved by load

Efficiency

Efficiency of a machine is a measure of its ability to perform work with minimal effort or energy and in the shortest possible time. It is expressed as a percentage, calculated by dividing the mechanical advantage by the velocity ratio.

Formula: Efficiency = (MA/VR) x 100%
