Tools / Lever
The most versatile tool to move loads. The principle is used in many other tools here described.
In engineering, levers are described by their three components:
- Load arm: Lever arm on the side of the load to be moved.
- Force arm: lever arm on the side of the moving force
- Pivot point: point around which the lever can rotate.
Using these terms, the law of leverage reads: "force times force arm equals load times load arm".
