Jump And Smile
The Jump & Smile is a type of fairground ride in which the chair cars are arranged on a number of radial arms around a central axis. As the central axis rotates, the arms are lifted into the air at pseudo-random intervals giving an erratic jumping motion. There is another version called Techno Jump, which had a specific pattern in which the cars would go up, one at a time, and then shake a little when up. Then the ride would suddenly drop up and down in order, creating the illusion of moving waves and the sound of piston A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms.

Also this ride would freeze in midair, making riders think it was over before starting to do the same jumping motion backwards. This ride is popular for most ages. References Am ...

Jumping Frog Detail, With Chair-O-Planes
Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne, by the relatively long duration of the aerial phase and high angle of initial launch. Some animals, such as the kangaroo, employ jumping (commonly called ''hopping'' in this instance) as their primary form of locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping. Physics All jumping involves the application of force against a substrate, which in turn generates a reactive force that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate, including ground or wa ...

Fairground Ride
Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people especially kids to create fun and enjoyment. Rides are often perceived by many as being scary or more dangerous than they actually are. This could be due to the design or from hearing about accidents involving rides that are similar. They are expected at most annual events such as fairs, traveling carnivals, and circuses around the world. Sometimes music festivals and concerts also host amusement park rides. Types of rides * Flat rides are usually considered to be those that move their passengers in a plane generally parallel to the ground, such as rides that spin around a vertical axis, like carousels and twists, and ground level rides such as bumper cars and The Whip. * Gravity rides are those where gravity is responsible for all or some of the movement, and where any vertical movement is not about a fixed point, such as roller coasters, water slides, and drop towers. ...

Pseudo-random
A pseudorandom sequence of numbers is one that appears to be statistically random, despite having been produced by a completely deterministic and repeatable process. Background The generation of random numbers has many uses, such as for random sampling, Monte Carlo methods, board games, or gambling. In physics, however, most processes, such as gravitational acceleration, are deterministic, meaning that they always produce the same outcome from the same starting point. Some notable exceptions are radioactive decay and quantum measurement, which are both modeled as being truly random processes in the underlying physics. Since these processes are not practical sources of random numbers, people use pseudorandom numbers, which ideally have the unpredictability of a truly random sequence, despite being generated by a deterministic process. In many applications, the deterministic process is a computer algorithm called a pseudorandom number generator, which must first be provided wi ...

Illusion
An illusion is a distortion of the senses, which can reveal how the mind normally organizes and interprets sensory stimulation. Although illusions distort the human perception of reality, they are generally shared by most people. Illusions may occur with any of the human senses, but visual illusions ( optical illusions) are the best-known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. For example, individuals watching a ventriloquist will perceive the voice is coming from the dummy since they are able to see the dummy mouth the words. Some illusions are based on general assumptions the brain makes during perception. These assumptions are made using organizational principles (e.g., Gestalt theory), an individual's capacity for depth perception and motion perception, and perceptual constancy. Other illusions occur because of biological sensory structures within the human body or conditions outside the body within one's phy ...

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ...
