Threads are provided in a simple screw jack to allow the movement to be calculated to a certain distance or height and to allow for less effort in lift.
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.
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 distance the object moves long the distance.
i have no clue. i need help on sci. homework.
Measure the distance from the fulcrum to the effort?
confusing
actually, the effort force would be decreasing, and the effort distance would be increasing!
When you multiply you x virable and you y virable that's your answer
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
