![]() The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. Examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Inclined planes are used to move heavy loads over vertical obstacles. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. ![]() Demonstration inclined plane used in education, Museo Galileo, Florence.Īn inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.
