The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.
Closely related to leveraging, the ratio is also known as risk, gearing or leverage. The two components are often taken from the firm's balance sheet or statement of financial position (so-called book value ), but the ratio may also be calculated using market values for both, if the company's debt and equity are publicly traded , or using a ...
There is therefore one specific gear ratio at which the car can achieve its maximum speed: the one that matches that engine speed with that travel speed. [1] At travel speeds below this maximum, there is a range of gear ratios that can match engine power to air resistance, and the most fuel efficient is the one that results in the lowest engine ...
A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.
The composite action test (double flank) is a method of inspection in which the work gear is rolled in tight double flank contact with a master gear or a specified gear, in order to determine (radial) composite variations (deviations). The composite action test must be made on a variable center distance composite action test device.
Mini hockey teams are made up of 6 players ( in the under-7s game ) or 7 players (in the under-9s game), of both sexes. Games consist of two 15-minute periods. To start the game, a face off is taken on the centre line. Each team is required to be in their own half prior to the ball being pushed.
Zone starts is the ratio of how many face-offs a player is on for in the offensive zone relative to the defensive zone. A player who has a high zone start ratio will often have increased Corsi numbers due to starting in the offensive zone, while a player with a low zone start ratio will often have depressed Corsi numbers.

Field hockey was introduced at the Youth Olympic Games at the inaugural edition in 2010 for both boys and girls. At the 2010 Games, field hockey was held in the outdoor format. From the 2014 Games, the Hockey 5s format, a 5-a-side tournament played on a smaller-sized field, has been used.
