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 ...

I was right! Yeah! Oh, my gosh!Yeah, spot-on.So, the further away you can apply that effort, that force,the easier it is to lift a loadbecause your lever is longer. OK!We're learning. I'm learning.

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 ...
