mechanical advantage

• Medida do ganho de força obtido pelo uso de uma ferramenta, dispositivo mecânico ou sistema de máquinas, calculada como a razão entre a força de saída e a força de entrada.

A measure of the force amplification achieved by using a tool, mechanical device, or machine system, calculated as the ratio of output force to input force.

1. Force multiplicationC1formal

   The ratio of the output force exerted by a machine to the input force applied to it, indicating how much a machine multiplies force.

   • A lever provides a mechanical advantage by allowing a small force to lift a heavy load.
   • The mechanical advantage of a pulley system is calculated by counting the number of rope segments supporting the load.
   • Engineers design gears to achieve a specific mechanical advantage in machinery.
