The 'ideal' mechanical advantage is length of the effort arm/length of the load arm .
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
The mechanical advantage of a lever is determined by the ratio of the effort arm to the resistance arm. In this case, the mechanical advantage would be 12 feet (effort arm) divided by 3 feet (resistance arm), resulting in a mechanical advantage of 4.
The mechanical advantage of a lever can be increased by either increasing the length of the lever or by changing the position of the fulcrum closer to the load.
A longer lever would typically have more mechanical advantage than a shorter lever. Mechanical advantage is calculated by dividing the length of the effort arm by the length of the resistance arm; therefore, the longer the effort arm, the greater the mechanical advantage.
The mechanical advantage of the lever can be calculated by dividing the output force (48 N) by the input force (12 N), which gives a mechanical advantage of 4. This means that the lever provides a mechanical advantage of 4, making it easier to lift the object.

The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
The mechanical advantage of a lever can be increased by either increasing the length of the lever or by changing the position of the fulcrum closer to the load.
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.
A longer lever would typically have more mechanical advantage than a shorter lever. Mechanical advantage is calculated by dividing the length of the effort arm by the length of the resistance arm; therefore, the longer the effort arm, the greater the mechanical advantage.
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
Crowbar (lever) .
The increase in work done by a lever is called mechanical advantage. It represents the ratio of the output force exerted by the lever to the input force applied to it. A lever with a higher mechanical advantage requires less input force to lift an object.
second class lever
The mechanical advantage of the lever can be calculated by dividing the output force (48 N) by the input force (12 N), which gives a mechanical advantage of 4. This means that the lever provides a mechanical advantage of 4, making it easier to lift the object.
