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.

The distance the object moves long the distance.
The distance between the effort and the fulcrum is known as the effort arm. It determines the amount of force required to move an object when using a lever. A longer effort arm requires less force to move the object, while a shorter effort arm requires more force.
Effort and distance have a direct relationship. The more distance you cover, the more effort you generally need to exert. This is because you are expending energy to travel a longer distance, which can lead to fatigue.
The trade-off between effort force and effort distance refers to the relationship where increasing the distance over which a force is applied (effort distance) can reduce the amount of force (effort force) needed to accomplish a task. This trade-off occurs in simple machines such as levers, where adjusting the distance from the pivot point affects the amount of force required to move an object. A longer effort distance allows for less force to be exerted, while a shorter distance requires more force.
The formula to calculate effort distance in mechanical advantage is Effort Distance = Load Distance / Mechanical Advantage. This means that effort distance is the distance over which the effort force is applied to move the load in a machine.
No, effort distance and resistance distance are not necessarily equal. Effort distance refers to the distance over which a force is applied, while resistance distance refers to the distance over which the load or resistance moves. In some cases, these distances may be equal, but in others they may differ depending on the mechanical system being analyzed.
The effort distance in a lever is measured from the point where the effort force is applied to the fulcrum. It is the distance over which the effort force acts to move the lever. By measuring this distance, you can calculate the mechanical advantage of the lever.
The distance between the lever's fulcrum and the input force is known as the effort arm. It determines the mechanical advantage of the lever system. The longer the effort arm, the easier it is to lift a heavier load.
