Question 42
INMCQ2 marksNeeds review
Four identical resistive strain gauges with gauge factor of 2.0 are used in a Wheatstone bridge as shown in the figure below. Only one of the strain gauges
changes its resistance due to strain. If the output voltage
is measured to be 1 mV, the magnitude of strain, in units of microstrain, is
