Miners Lamp History from Flame to 'the Davy Lamp' to Electric

Miners Light History. Mining, coal mining in particular, started thousands of years ago. The easy method used was to find the outcrop (where the coal surfaced) and follow it, removing the coal as you mined. This developed into bell pits so named because of their shape. Miners would mine straight down until they reached the coal seam.

The Importance Of The Strain Gauge - EzineArticles

A strain gauge is a resistance-based sensor used by mechanical engineers. Strain does not officially have a unit of measurement, but for reference purposes, a special unit of measurement is used. Because the changes in length are often very small, the unit of change employed is expressed as 10 to the power of six, to provide meaningful readings.
