An inclined plane, also known as a girolamo cardano accomplishments, 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.

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. Two other simple machines are often considered to be derived from the inclined plane. The wedge can be considered a moving inclined plane or two inclined planes connected at the base. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks, ships and planes. Wheelchair ramps are used to allow people in wheelchairs to get over vertical obstacles without exceeding their strength.

Other inclined planes are built into permanent structures. Roads for vehicles and railroads have inclined planes in the form of gradual slopes, ramps, and causeways to allow vehicles to surmount vertical obstacles such as hills without losing traction on the road surface. Johnstown Inclined Plane, a funicular railroad. The portion of the chain hanging below the inclined planes is symmetrical, with an equal number of beads on each side. It exerts an equal force on each side of the string. Since the beads are at equal intervals on the string, the total number of beads supported by each plane, the total load, is proportional to the length of the plane.

As pointed out by Dijksterhuis, Stevin’s argument is not completely tight. The forces exerted by the hanging part of the chain need not be symmetrical because the hanging part need not retain its shape when let go. Inclined planes have been used by people since prehistoric times to move heavy objects. However the inclined plane was the last of the six classic simple machines to be recognised as a machine. It wasn’t until the Renaissance that the inclined plane was classed with the other simple machines.
