Seesaw in 1792 painting by Francisco de Goya A set of conjoined playground seesaws. A seesaw (also known as a teeter-totter) is a long, narrow board supported by a single pivot point, most commonly located at the midpoint between both ends; as one end goes up, the other goes down. These are most commonly found at parks and school playgrounds.
Playground slides are found in parks, schools, playgrounds and backyards. The slide is an example of the simple machine known as the inclined plane, [1] [circular reference] which makes moving objects up and down easier, or in this case more fun. The slide may be flat, or half cylindrical or tubular to prevent falls.
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 ...
Early pleasure wheel in Russia, 1807. Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people to create fun and enjoyment. ...
A merry-go-round at a park in New Jersey. A simplified drawing of various older types of roundabout to be found in British playgrounds. A roundabout (British English), merry-go-round (American English), or carousel (Australian English), is a piece of playground equipment, a flat disk, frequently about 2 to 3 metres (6 ft 7 in to 9 ft 10 in) in diameter, with bars on it that act as both hand ...
Wheelchair ramp, Hotel Montescot, Chartres, France Demonstration inclined plane used in education, Museo Galileo, Florence.. An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.
A Rube Goldberg machine, named after American cartoonist Rube Goldberg, is a chain reaction–type machine or contraption intentionally designed to perform a simple task in an indirect and (impractically) overly complicated way. Usually, these machines consist of a series of simple unrelated devices; the action of each triggers the initiation ...
Like the other simple machines a screw can amplify force; a small rotational force on the shaft can exert a large axial force on a load. The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force).
