Description: An inclined plane is a flat surface that lies at an angle relative to level ground used to form a ramp to raise and lower a load. The load can be as simple as a person, i.e. walking up a ramp, or larger such as trains hauling materials along a graded track. The steepness and length of the plane help to distribute weight and reduce work that is needed to lift or lower materials from one elevation to another.
Recommended Class: 4th to 7th
