Engineering ratios

Close-ratio transmission

A close-ratio transmission describes a motor vehicle transmission with a smaller than average difference between the gear ratios. They are most often used on sports cars in order to keep the engine in the power band. There is no industry standard as to what constitutes a close-ratio transmission, a transmission that one manufacturer terms close-ratio may not necessarily be considered close-ratioed by another manufacturer. Generally speaking, the more gears a transmission has, the closer they are together. A continuously variable transmission has a near infinite "number" of gear ratios, which implies an infinitely close-ratio between gears. However, with no specific gear ratios, it would not be considered a close-ratioed transmission. (Wikipedia).

Ratios Introduction - what are ratios?

Ratios are used to compare different quantities. In this introduction to ratios we will look at what ratios are, how we deal with ratios of different measurement units and that ratios can be simplified. To donate to the tecmath channel:https://paypal.me/tecmath To support tecmath on Pa
