Home > Mechanical efficiency

In physics, mechanical efficiency is the effectiveness of a simple machine.

The formula for finding efficiency is,

Efficiency = AMA ÷ IMA

where AMA equals actual mechanical advantage and IMA equals ideal mechanical advantage.

Efficiency is measured as a percentage. The efficiency of an ideal machine is 100%. Therefore, all real machine efficiencies are less than 100%.

Mechanical engineeringMechanical engineering is the application of physical principles to the creation of useful devices, objects and machines. Mechanical engineers use principles such as heat, force, and the conservation of mass and energy to analyze static and dynamic physic	Mechanical advantageIn physics and engineering mechanical advantage (MA is the factor by which a machine multiplies the force put into it. The mechanical advantage can be calculated for the following simple machines by using the following formulas: Lever: MA length of effort	Mechanically induced modulationMechanically induced modulation is an oOptical signal modulation induced by mechanical means. An example of deleterious mechanically induced modulation is speckle noise created in a multimode fiber by an imperfect splice or imperfectly mated connectors.
Mechanical equilibriumA standard definition of mechanical equilibrium is the state of a mechanical system in which the sum of the forces on each particle of the system is zero. However, this definition is of little use in continuum mechanics, for which the idea of a particle i	Mechanical workWork (abbreviated W is the energy transferred in applying force over a distance. Work can be calculated from the formula: : : where F is the force. s is the position. Readers not familiar with vectors and calculus please see "Simpler Formulae" below.
