The gauge is simply bonded or glued to an object such as metal, plastic, wood or composite materials to measure surface strain. Measurement of this strain with a secondary transducer like a strain gauge ( metallic conductor) becomes a measure of the appilied pressure. I've done some research about strain gauges, but the only helpful information involves when they are part of a load cell. View Answer, 8. a. as a ratio of strain in lateral direction to the strain in an axial direction b. as a ratio of strain in axial direction to the strain in lateral direction c. as a ratio of stress in axial direction to the strain … Invented in 1938, a strain gauge is used to measure stress, strain and other force-related parameters such as torque, acceleration, pressure, and vibration. Measurement of Pressure, Flow, Temperature and Liquid Level. View Answer, 7. Under force-current analogy, viscous friction coefficient is considered analogous to: A. The strain gauge is not bonded to the specimen. These cookies do not store any personal information. How is the Poisson's ratio expressed for a wire in terms of assorted directions? Dialymotion View Answer. The device is less robust than the bonded gauge and was developed at a time when the bounding technique was not reliable. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. 1. Join our social networks below and stay updated with latest contests, videos, internships and jobs! 2.1. View Answer, 10. d) 8 types I plan on attaching the strain gauge to the cable supporting the string, soldering longer wires to the strain gauge, and connecting it to an Arduino Uno. View mcq A strain gauge bridge measures the strain in a cantilever where the gauge is fixed, with strain , the gauge resistance increases from . Hope this is of help.
