How does the length of effort arm affect the amount of effort needed to lift an object?

The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher
must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense
of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no
effect on the quantity of work.

How much effort is needed if the length of the inclined plane is shorter?
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.

Do machines decrease the amount of energy that is needed to do work?
Not usually. They can convert effort into distance and things like that, but the overall energy is about the same.

they were needed
What is the formula for Effort needed?
If you are thinking of Effort as the FORCE required to move an Object, then the formula is: F = M x A, force = Mass x Acceleration If you are thinking of Effort as the amount of WORK done (in Scientific terms), then the formula is: Work = Force x Distance
