The Olympiad train is driven by b1, b2, l1, l2, m1, m2, n1, n2, and o1, which mounts the pointer. It has a computed modelled rotational period of exactly four years, as expected. It is the only pointer on the mechanism that rotates counter-clockwise; all of the others rotate clockwise. [6] [9] [77]
The Geneva drive or Geneva mechanism is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel ( driven wheel) that advances it by one step at a time. The drive wheel also has an elevated circular ...
A gear train or gear set is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. [ 2 ]
A replica of the DeLorean time machine's Mr. Fusion Home Energy Reactor. The Mr. Fusion Home Energy Reactor is the name of a power source used by the DeLorean time machine in the Back to the Future trilogy. It can be seen for the first time at the end of Back to the Future when Doc pulls into the McFly's driveway after a trip to the year 2015.
Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions. 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 ...
In 38 countries, including the U.S., you can already find train routes when you search specifically for them, but Google will be bringing up those options along with bus travel times when you ...
Clockwise. Two-dimensional rotation can occur in two possible directions or senses of rotation. Clockwise motion (abbreviated CW) proceeds in the same direction as a clock 's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in ...
Google Street View is a technology featured in Google Maps and Google Earth that provides interactive panoramas from positions along many streets in the world. It was launched in 2007 in several cities in the United States, and has since expanded to include all of the country's major and minor cities, as well as the cities and rural areas of many other countries worldwide.
