1. Work performed by a mechanical force or system; in physics, the product of force and displacement in the direction of that force
The mechanical work done by the engine lifted the car up the hill.
O trabalho mecânico realizado pelo motor elevou o carro pela colina.
2. Labor involving the operation, repair, or maintenance of machines or mechanical systems
He spent the day doing mechanical work on the automobile.
Ele passou o dia fazendo trabalho mecânico no automóvel.
3. In engineering and physics, work calculated as W = F × d × cos(θ), where F is force, d is displacement, and θ is the angle between them
The mechanical work equals the force applied multiplied by the distance moved in the direction of the force.
O trabalho mecânico é igual à força aplicada multiplicada pela distância percorrida na direção da força.
