In physics, moment is a combination of a physical quantity, like force, and a distance. For example, a moment of force is the product of of a force and its distance from an axis, which causes rotation about the axis.
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.

increasing the distance
If the input force is applied at a greater distance than the length of the effort arm is increased thereby reducing the effort.
actually, the effort force would be decreasing, and the effort distance would be increasing!
work (effort) equals load times distance

The effort-to-load force in a first class lever is decreased when the distance between the effort and the fulcrum is less than the distance between the fulcrum and the load.

mass and distance
AMA=force produced/force applied TMA=distance effort moves/distance load moves
That's the definition of "work" ... (force exerted) times (distance through which the force acts). If you push against the end of a lever with a force 'F' and move it through a distance 'D', then (F x D) is the work you put into the lever.
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
