The most readily observable case of the Magnus effect is when a spinning sphere (or cylinder) curves away from the arc it would follow if it were not spinning. It is often used by football and volleyball players, baseball pitchers, and cricket bowlers. Consequently, the phenomenon is important in the study of the physics of many ball sports.
A double-end Euler spiral. The curve continues to converge to the points marked, as t tends to positive or negative infinity. An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). This curve is also referred to as a clothoid or Cornu spiral.
The wheel is placed in contact with the curved line to be measured and run along its length. By counting the number of teeth passing a mark on the handle while this is done, the length of the line can be ascertained: line length = wheel circumference × teeth counted/teeth on wheel.
It accounts for the "wagon-wheel effect", so-called because in video, spoked wheels (such as on horse-drawn wagons) sometimes appear to be turning backwards. A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light , is an example of the stroboscopic effect being applied to a cyclic motion that is not ...
Blitzball is played with a ball similar to a wiffle ball, which curves more when pitched and travels further when hit than a regular baseball. [38] There are only 2 to 3 players on each team, [39] and games last 3 innings. [40] It was started around 2010. [41]
The wheels of the power car, however, can be affected by hunting oscillation, because the wheels of the power car are fixed to the axles in pairs like in conventional bogies. Less conical wheels and bogies equipped with independent wheels that turn independently from each other and are not fixed to an axle in pairs are cheaper than a suitable ...
In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).
In the third edition of The Dickson Baseball Dictionary, "shoot" is explained as: . Shoot 【noun / obsolete】 A kind of thoroughly changing pitching.It was a term used from the 19th century to the beginning of the 20th century and it was called as a curve or a variant thereof because the sphere moved "in a certain direction" ("roughly").
