The higher the fulcrum, the farther it will become.
Changing the position and height of the fulcrum will affect the effect of the lever. When the distance between the fulcrum and the power action line is greater than the distance between the fulcrum and the resistance action line, the lever saves effort. The magnitude, direction, acting point and fulcrum position of the force will affect the balance of the lever, and the changes of the fulcrum, direction and acting point of the force can be reflected through the force arm.
