A strain gage bridge has a strain gage of resistance
are fixed resistors also rated at 200 Ω. The strain gage experiences a tensile strain of 400 microstrain due to the displacement of an object. Determine the change in resistance ?R of the strain gage. If the input voltage is Vi volts then determine the change in output voltage ?Vo.
