The power input is equal to the power output, ignoring losses due to friction, wear, and bending of the lever beam. Power is force multiplied by velocity and they differ proportionately from each ...

The longer the lever, and the further the effort acts from the pivot, the greater the force on the load will be - it is easier to use a longer spanner when trying to turn a nut, and easiest to ...

apply the moment equation and identify common levers and applications of moments. Hooke's law Learn about Hooke's Law and about the spring constant of a spring as being the amount of force needed ...
