The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
Stroboscopic effect is one of the particular temporal light artefacts. In common lighting applications, the stroboscopic effect is an unwanted effect which may become visible if a person is looking at a moving or rotating object which is illuminated by a time-modulated light source.
The stroboscopic effect makes each seem to be a single animated object. By allowing the rotation speed to be slightly out of synchronization with the strobe, the animated objects can be made to appear to also move slowly forwards or backwards, according to how much faster or slower each rotation is than the corresponding series of strobe flashes.
The Skywheel is a ride that is essentially a double Ferris Wheel with each wheel attached on each end of a large boom that rotates on its axis causing the wheels to rise and fall while rotating independently as they rotate around the boom axis causing a gravitational thrill more spectacular than a normal Ferris Wheel.
Wheels can also lose traction when surface conditions reduce available traction such as on snow and ice. As an open differential delivers only enough torque to cause the "weakest" wheel to spin, if one drive wheel is stationary on a low traction surface (mud, ice, etc.), the deliverable torque is limited to the traction available on it.
This makes them extraordinarily appealing to collectors, who want to own the very first copies of a work, says Vasilis Terpsopoulos, manager of the rare book department at New York City's Strand ...
The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid. A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object.
Footage captures the moment fairgoers in Florida were stuck upside-down on a Ferris wheel ride that malfunctioned. The attraction, which features enclosed carriages that swing and flip, slowed ...
