The load arm of a lever is the distance between the fulcrum (pivot point) and the point where the load or resistance is applied. It determines how effectively a lever can lift or move a load. A longer load arm typically results in a greater mechanical advantage, making it easier to lift heavy objects.
determined by the length of the lever arm and the weight of the load. The longer the lever arm, the less force is needed to lift the load. The force needed is inversely proportional to the length of the lever arm.
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
Keeping the lower arm of the lever in a horizontal position after applying the load ensures that the lever is balanced, allowing for efficient and effective use of the lever's mechanical advantage to lift the load. If the lower arm is not horizontal, the lever may become unbalanced, making it difficult to control the load and potentially causing accidents.
The force that pushes on one arm of a lever is called the effort force. This force is applied to overcome the resistance force, which is the force exerted by the load on the other arm of the lever. The lever then magnifies the effort force to lift or move the load.

The end of a lever that carries the load is the output arm instead of the input arm which is the end of a lever that force is applied to move the load.

load arm, effort arm, load, effort, fulcrum!
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
Keeping the lower arm of the lever in a horizontal position after applying the load ensures that the lever is balanced, allowing for efficient and effective use of the lever's mechanical advantage to lift the load. If the lower arm is not horizontal, the lever may become unbalanced, making it difficult to control the load and potentially causing accidents.

What is the function of each part of the lever
To find the mechanical advantage (MA) of a lever, you can calculate it by dividing the length of the effort arm by the length of the load arm. The formula is MA = Le / Ll, where Le is the length of the effort arm and Ll is the length of the load arm.
