In physics, jerk or jolt is the rate at which an object's acceleration changes with respect to time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s3 (SI units) or standard gravities per second (g0/s).
Rotation, or spin, is the circular movement of an object around a central axis. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions.
Robert Craig Knievel, known professionally as Evel Knievel, was an American stunt performer and entertainer. Throughout his career, he attempted more than 75 ramp-to-ramp motorcycle jumps. Knievel was inducted into the Motorcycle Hall of Fame in 1999. He died of pulmonary disease in Clearwater, Florida, in 2007, aged 69.
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
The Fosbury flop is a jumping style used in the track and field sport of high jump. It was popularized and perfected by American athlete Dick Fosbury, whose gold medal in the 1968 Summer Olympics in Mexico City brought it to the world's attention. The flop became the dominant style of the event; before Fosbury, most elite jumpers used the straddle technique, Western Roll, Eastern cut-off or scissors jump to clear the bar. Though the backwards flop technique had been known for years before Fosbury, landing surfaces had been sandpits or low piles of matting and high jumpers had to land on their feet or at least land carefully to prevent injury. With the advent of deep foam matting, high jumpers were able to be more adventurous in their landing styles and hence experiment with styles of jumping.
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together.
Automobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road. It is commonly judged by how a vehicle performs particularly during cornering, acceleration, and braking as well as on the vehicle's directional stability when moving in steady state condition.
Test Track is a high-speed slot car thrill ride located in World Discovery at Epcot, a theme park at the Walt Disney World Resort in Bay Lake, Florida. The ride is a simulated excursion through the rigorous testing procedures that General Motors uses to evaluate its concept cars, culminating in a high-speed drive around the exterior of the attraction.
World of Motion, presented by General Motors, was the former occupant of the transportation pavilion in Epcot at Walt Disney World Resort. It was an opening day attraction at EPCOT Center in 1982 and it closed in 1996 to make way for Test Track, a new thrill ride through a GM testing facility.
A motion simulator or motion platform is a mechanism that creates the feelings of being in a real motion environment. In a simulator, the movement is synchronised with a visual display of the outside world (OTW) scene. Motion platforms can provide movement in all of the six degrees of freedom (DOF) that can be experienced by an object that is free to move, such as an aircraft or spacecraft:. These are the three rotational degrees of freedom and three translational or linear degrees of freedom.
The Orbiter is a fairground ride, which involves a number of cars spun by a rotating axis. The ride was first presented to the public in the summer of 1976, at Margate Dreamland's Amusement Park.
Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true. Alignment angles can also be altered beyond the maker's specifications to obtain a specific handling characteristic. Motorsport and off-road applications may call for angles to be adjusted well beyond normal, for a variety of reasons.
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. They bionically resemble the ball-and-socket joints found in most tetrapod animals.
Breakdance is an amusement ride designed by Huss Maschinenfabrik GmbH & Co. KG in 1985.
The Octopus is a type of amusement ride in the shape of an octopus. Five to eight arms attached to a central axis of rotation and move up and down in a wavelike motion, while cars at the end of the arms, either attached directly to the arm or fixed on spinning crosses, spin freely or stay in place, depending on the exact type of ride. Each Octopus ride has the arms attached the middle of the ride. The middle or centric of the ride will move somehow. Most octopus rides require guests to be at least 42 inches to ride without an adult; smaller children must have an adult with them. This is a regular at the annual AGS and AHS fairs in Ateneo de Manila University
The Funtastic World of Hanna-Barbera was a simulator ride at Universal Studios Florida and one of the park's original attractions. The story line tells that Dick Dastardly and Muttley have kidnapped Elroy Jetson. Yogi Bear and Boo-Boo give chase and the audience is in for the ride of their lives. The attraction opened on June 7, 1990 and closed on October 20, 2002.
Ride & Show Engineering, Inc. is an American private company that conceptualizes, develops, and builds attractions, show action equipment, and transportation systems. In 1984 Eduard Feuer and William Watkins, the former Senior Project Engineer and Chief Mechanical Engineer, respectively, for Walt Disney Imagineering, established Ride & Show in the state of California.
In Newtonian mechanics, the centrifugal force is an inertial force that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force F on an object of mass m at the distance r from the origin of a frame of reference rotating with angular velocity ω is:
Sledge Hammer is a ride at Canada's Wonderland. The Huss ride was opened to the public on May 4, 2003, and continues to operate today. Sledge Hammer is also the world's first and only 'giant jumping machine'. The ride has had serious mechanical issues, causing repeated closures.
