Class 1 Levers: Effort and Load Direction
A Class 1 lever is defined by the position of the fulcrum, which lies between the effort (input force) and the load (output force or resistance).
Effort and Load Movement
- When you apply the effort to one end of the lever, the load at the other end moves.
- Typically, in a Class 1 lever, applying downward force (effort) causes the load to move upward. Conversely, lifting the load requires applying effort in the opposite direction.
- Therefore, the effort and the load move in opposite directions.
This principle applies regardless of whether the lever provides a mechanical advantage or disadvantage.
