A pulley or pliers
Simple machines increase mechanical advantage.
Increase the advantage.
You can increase the mechanical advantage of a pulley system by adding more pulleys to the setup. As the number of pulleys increases, the mechanical advantage also increases. This allows you to lift heavier loads with less force.
To increase the mechanical advantage of a third-class lever, you can adjust the distances between the effort force, the fulcrum, and the load. By increasing the length of the effort arm or decreasing the length of the load arm, you can increase 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.
To increase the mechanical advantage of a wheel and axle system, you can either increase the radius of the wheel or decrease the radius of the axle. This will result in a greater difference in radii, which enhances the mechanical advantage. Additionally, reducing friction in the system can also improve its overall efficiency.
The spokes of a wheel are comparable to levers. Longer spokes give more mechanical advantage. Even in a wheel that is solid, and has no spokes, the greater the diameter, the greater the mechanical advantage.
No, not all levers have a mechanical advantage. The mechanical advantage of a lever depends on the specific positions of the effort, load, and fulcrum. Some levers may have a mechanical advantage of less than 1, resulting in a decrease in force but an increase in distance.
Increasing the distance between the pivot point and the effort force, or decreasing the distance between the pivot point and the load, could increase the mechanical advantage of a second-class lever. Additionally, using a longer lever arm can also increase the mechanical advantage.
