Expert Solution

Explanation:

Answer: An inclined plane.

With less effort than if it were lifted straight up, an item can be raised or lowered from one level to another using an inclined plane, which is a flat surface that slopes at an inclination from the horizontal. It is a straightforward device that lifts objects with less force thanks to the leverage principle. Ramps, sloping sidewalks, and staircases are a few examples of inclined planes. You use an inclined plane to modify your height as you climb or descend stairs. The stairs' slope decreases the power needed to move vertically, making it simpler to climb or descend them than to raise yourself up or down.
