   This gauge is represented by the EM Society (in full, Eighteen Millimetre Society). 00 track (16.5 mm) is the wrong gauge for 1:76 scale, but use of an 18.2 mm (0.717 in) gauge track is accepted as the most popular compromise towards scale dimensions without having to make significant modifications to ready-to-run models. Has a track gauge ...

6. Track gauge in the United States - Wikipedia

   Some railways, primarily in the northeast, used standard gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft ( 1,524 mm ), while northern railroads that were not standard-gauge tended to be narrow-gauge.

7. Load cell - Wikipedia

   en.wikipedia.org/wiki/Load_cell

   A strain gauge sensor measures the deformation of the elastic element, and the output of the sensor is converted by an electronic circuit to a signal that represents the load. Capacitive strain gauges measure the deformation of the elastic material using the change in capacitance of two plates as the plates move closer to each other.

9. Crack tip opening displacement - Wikipedia

   en.wikipedia.org/wiki/Crack_tip_opening_displacement

   A type of strain gauge called a crack-mouth clip gage is used to measure the crack opening. [3] The crack tip plastically deforms until a critical point after which a cleavage crack is initiated that may lead to either partial or complete failure. The critical load and strain gauge measurements at the load are noted and a graph is plotted.
