How can the mechanical advantage of a lever be increased?

You would adjust the relative placement of the load, fulcrum, and the force.
Explanation:
I will discuss only class 1 and class 2 levers because the best you can get from a class 3 lever is a mechanical advantage of 1.

Class 1 Levers:
- Moving the fulcrum closer to the load will increase the mechanical advantage.
- Moving the effort farther from the fulcrum will increase the mechanical advantage. This may require a longer lever.
Class 2 Levers:
- Moving the load closer to the fulcrum will increase the mechanical advantage.
- Moving the effort farther from the fulcrum will increase the mechanical advantage. This may require a longer lever.
I hope this helps,
