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.
The longer the effort arm, the less effort is needed to lift an object. This is because a longer effort arm increases the leverage, allowing the force to be distributed over a greater distance. Consequently, less force is required to overcome the resistance of the load.
The ratio of the effort-to-load forces is the reciprocal of
the lengths of the corresponding lever arms.

A pulley is a force multiplier. (it swaps force for distance).
The effort of a lever is the force applied to the lever to move an object. It is the force needed to overcome the resistance of the load being lifted or moved by the lever. The relationship between the effort and the load is determined by the length of the lever arms.
the differrence between these two kinds of things is that they both have the weight in tthem

An inclineded plane
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.

Not usually. They can convert effort into distance and things like that, but the overall energy is about the same.

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
