In what way does a wedge operate as a simple machine?

A wedge operates as a simple machine by changing the direction of the applied force, turning it into a perpendicular force. When force is applied to the top of the wedge, it is directed downward, causing the wedge to split or separate materials along its inclined surfaces. This action efficiently translates the input force into two outward forces that act at an angle, enabling the materials to be split apart or pushed apart effectively. The unique shape of the wedge allows it to concentrate the applied force over a small area, enhancing its effectiveness in tasks like cutting or lifting.

This functionality is also fundamental to understanding other simple machines, such as the screw or ramp, where the transfer of force direction plays a crucial role in achieving mechanical advantage. By using a wedge, one can exert a greater influence on an object than could be achieved with the same amount of force applied directly.
