The figure of merit which describes the overall behaviour of the wire under stress is determined from?(a) elastic modulus(b) gauge factor(c) elastic factor(d) gauge resistanceI had been asked this question by my college director while I was bunking the class.Enquiry is from Pressure Transducers in division Physiological Transducers of Biomedical Instrumentation

Answer»

The correct ANSWER is (b) gauge factor

The explanation: The figure of merit which DESCRIBES the overall behaviour of the wire under stress is determined from the gauge factor of the wire. Gauge factor gives information on the EXPECTED resistance change or output SIGNAL at maximum permissible elongation.the gauge factor determines to a large extent the sensitivity of the wire when it is made into a practical strain gauge.
