1) A compressive force is applied to a structural member. Two separate strain gauges are attached to the structural member; one is a nickel wire strain gauge having a gauge factor of -12.1 and the other is nichrome wire strain gauge having a gauge factor of 2. Calculate the value of resistance of the two gauges after they are strained, if the resistance of strain gauges before being strained is 120 N, and the compressive strain is 5 micro-strain. Assume positive value for tensile strain and negative for compressive strain.
