Whichever has the greater Mechanical Advantage.
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
They are types of screws which are actually inclined planes that curve around the outside of a rod and the interior of a cylinder. Instead of anchoring into a surface, a bolt passes through a hole and is locked in place by the nut. At its most basic, it is an inclined plane. That inclined plane formed by the threads of the bolt is wrapped around an axle and the nut provides a mechanical advantage by being a lever (The force arm is the nut's radius). The lever can be extended (a wrench) to provide greater mechanical advantage.
The 'ideal' mechanical advantage is length of the effort arm/length of the load arm .
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
Whichever has the greater Mechanical Advantage.
Simple machines, such as a lever, inclined plane, or wheel and axle, give you a mechanical advantage.You calculate the mechanical advantage of a simple machine by dividing the output force by the input force.
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.

Crowbar (lever) .
Those dependent on the vector resolution of forces (inclined plane, wedge, screw) and those in which there is an equilibrium of torques (lever, pulley, wheel).
