Which simple machine is used to convert rotational motion to linear motion? Lever Screw Pulley Wedge

The simple machine that is used to convert rotational motion to linear motion is the **wedge**. A wedge is a device that consists of two inclined planes joined back to back, forming a sharp edge. When force is applied to the wedge, it splits or separates objects by converting the rotational motion of the handle into linear motion along the inclined planes. This is how a wedge functions to drive objects apart.
