Seesaw
A seesaw (also sometimes known as a teeter-totter in North America) 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. Mechanics Mechanically, a seesaw is a lever which consists of a beam and fulcrum with the effort and load on either side. Varieties The most common playground design of seesaw features a board balanced in the center. A person sits on each end, and they take turns pushing their feet against the ground to lift their side into the air. Playground seesaws usually have handles for the riders to grip as they sit facing each other. One problem with the seesaw's design is that if a child allows himself/herself to hit the ground suddenly after jumping, or exits the seesaw at the bottom, the other child may fall and be injured. For this reason, seesaws are often mounted above a soft surface such as foa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playground Equipment
A playground, playpark, or play area is a place designed to provide an environment for children that facilitates play, typically outdoors. While a playground is usually designed for children, some are designed for other age groups, or people with disabilities. A playground might exclude children below (or above) a certain age. Modern playgrounds often have recreational equipment such as the seesaw, merry-go-round, swingset, slide, jungle gym, chin-up bars, sandbox, spring rider, trapeze rings, playhouses, and mazes, many of which help children develop physical coordination, strength, and flexibility, as well as providing recreation and enjoyment and supporting social and emotional development. Common in modern playgrounds are ''play structures'' that link many different pieces of equipment. Playgrounds often also have facilities for playing informal games of adult sports, such as a baseball diamond, a skating arena, a basketball court, or a tether ball. Public playground equ ...

When performed as a spectacle, acrobatic tricks such as flips or skipping rope while in the air are often included. It is thought that women developed to see over the walls that surrounded their homes, as women in traditional Korea were rarely allowed out of their living compounds, except at night. According to a legend, a wife who wanted to see her husband, trapped in a prison beyond a high wall, could catch a glimpse of her husband's face by using a in collaboration with another prisoner's wife.

Swing (seat)
A swing is a seat or platform, suspended from chains, ropes, or bars, on which one or more people can swing back and forth for enjoyment or relaxation. Swings are a common piece of equipment at children's playgrounds and may also be found in yards or gardens, on porches, inside homes (for example, the Indian oonjal), or as freestanding public play equipment like the Estonian village swing. Swings have a long history in many different parts of the world and come in various types. On playgrounds, several swings are often suspended from a shared metal or wooden frame, known as a swing set, allowing more than one child to play at a time. Such swings come in a variety of sizes and shapes. For infants and toddlers, swings with leg holes support the child in an upright position while a parent or sibling pushes the child to get a swinging motion. Some swing sets include play items other than swings, such as a rope ladder or sliding pole. For older children, swings are sometimes made of a ...

Teeterboard
The teeterboard or Korean plank is an acrobatic apparatus that resembles a playground seesaw. The strongest teeterboards are made of oak (usually 9 feet in length). The board is divided in the middle by a fulcrum made of welded steel. At each end of the board is a square padded area, where a performer stands on an incline before being catapulted into the air. The well-trained flyer performs various aerial somersaults, landing on padded mats, a human pyramid, a specialized landing chair, stilts, or even a Russian bar. The teeterboard is operated by a team of flyers, catchers, spotters and pushers. Some members of the team perform more than one acrobatic role. In the early 1960s the finest teeterboard acts, trained in the Eastern Bloc countries, performed with Ringling Brothers and Barnum & Bailey Circus. Korean-style teeterboard called Neolttwigi is a form of teeterboard where two performers jump vertically in place, landing back on the apparatus instead of dismounting onto ...

Lever
A lever is a simple machine consisting of a beam (structure), beam or rigid rod pivoted at a fixed hinge, or '':wikt:fulcrum, fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load, and effort, the lever is divided into Lever#Types of levers, three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English language, English around 1300 from . This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to , itself from the adjective ''levis'', meaning "light" (as in "not heavy").
