This science ClipArt gallery offers 16 illustrations of a simple machine, inclined planes. Inclined planes are surfaces whose endpoints have different heights, and by moving an object up the plane, it eliminates the need to move the object completely vertical, reducing work.

"An inclined plane is a slope, or a flat surface, making an angle with a horizontal line...the force acts at an angle to the plane or to the base." —Hallock 1905

"Suppose the inclined plane, to be two feet from A to B, and one foot from C to B, then, as we have already seen, a power of one pound at P, would balance a weight of two pounds at W." -Comstock 1850

"Suppose two inclined planes, of the same height, with bases of different lenghts; then the weight and power will be to each other as the lenght of the planes." -Comstock 1850

"A force pushing a weight from C to D, only raises it through the perpendicular height, E D, by acting along the whole length of the plane, C D; and if the plane be twice as it is high, one pound at B, acting over the pulley, D, would balance two pounds at A, or any where on the plane; and so of all other quantities and proportions." — Goodrich, 1844

"The power required to force a given weight up an inclined plane, is in proportion to its height, and the length of its base, or in other words, the force must be in proportion to the rapidity of its inclination." -Comstock 1850'
