Measure the distance from the fulcrum to the effort?

You can make any relationship you want between the effort distance and the load (resistance) distance. If you make them equal, then your lever has no mechanical advantage.
The effort required would be proportional to the resistance.
The distance the object moves long the distance.
Mechanical disadvantage occurs if the load distance is greater than the effort distance, then the effort required is more than the load being moved. It is also known as a 'negative mechanical advantage'.

actually, the effort force would be decreasing, and the effort distance would be increasing!

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

It rotates freely until it is required to do work. As soon as a load is placed across the output more effort will be required to rotate the Dynamo.
You can make any relationship you want between the effort distance and the load (resistance) distance. If you make them equal, then your lever has no mechanical advantage.
Effort is lost in friction .
