Want to thank tfd for its existence.

Mechanical advantage force amplifying effectiveness of a simple machine such as a lever an inclined plane a wedge a wheel and axle a pulley system or a jackscrew. A mechanical advantage is the amount of help you can get from using a machine to do something instead of just doing it with purely your own strength. Mechanical advantage is a measure of the force amplification achieved by using a tool mechanical device or machine system. Mechanical advantage definition is the advantage gained by the use of a mechanism in transmitting force.

Mechanical advantage is defined as the resistance force moved divided by the effort force used. The theoretical mechanical advantage of a system is the ratio of the force that performs the useful work to the force applied assuming there is no friction in the system. Published by houghton mifflin harcourt publishing company. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force.

The american heritage science dictionary copyright 2011. The ratio of the force that performs the useful work of a machine to the force that is applied to the machine. Mechanical advantage the ratio of the force exerted by a machine to the force applied to it ratio the relative magnitudes of two quantities usually expressed as a quotient based on wordnet 3 0 farlex clipart collection. In the lever example above for example a person pushing with a force of 30 lb 13 5 kg was able to move an object that weighed 180 lb 81 kg.
