[1] [2] [3] The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move heavy loads over vertical obstacles. 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. [3]
A simple machine is a mechanical device that changes the direction or magnitude of a force. [1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. [2] Usually the term refers to the six classical simple machines that were defined by Renaissance scientists: [3] [4 ...
A spiral slide is a playground slide that is wrapped around a central pole to form a descending spiral forming a simple helter skelter. A wavy slide is a slide that has waves in its shape, causing the person sliding to go up and down slightly while descending. A tube slide is simply a slide in the form of a tube. It can also curve or have bumps.
The hand axe is the first example of a wedge, the oldest of the six classic simple machines, from which most machines are based. The second oldest simple machine was the inclined plane (ramp), [6] which has been used since prehistoric times to move heavy objects. [7] [8] The other four simple machines were invented in the ancient Near East. [9]

From the time of Archimedes to the Renaissance, mechanisms were viewed as constructed from simple machines, such as the lever, pulley, screw, wheel and axle, wedge, and inclined plane. Reuleaux focused on bodies, called links, and the connections between these bodies, called kinematic pairs, or joints.
A wedge is a triangular shaped tool, a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular to its inclined
It has been claimed [59] that these sketches show that Cayley modeled the principles of a lift-generating inclined plane as early as 1792 or 1793. In 1796, Cayley made a model helicopter of the form commonly known as a Chinese flying top, unaware of Launoy and Bienvenu's model of similar design. He regarded the helicopter as the best design for ...
