2. A Wheatstone Bridge is used to condition the output from a strain gauge with a base resistance of 250 2. The resistors in the bridge match the strain gauge base resistance. The gauge factor of the strain gauge 2=1.5 and it is firmly affixed to the pillar of a suspension bridge that is manufactured from mild steel (E=210 GPa). Assuming that the average stress in the pillar is 482 MPa and the supply voltage is 15 V, calculate the output voltage from the Wheatstone Bridge.
