A Wheatstone bridge has a single strain gauge in one arm and the other arms are resistors with each having the same resistance as the unrestrained gauge. Show that the output voltage from the bridge is given by 1/4 V _S Ge, V ₃ , where is the supply voltage to the bridge, G is the gauge factor of the strain gauge, and e is the strain acting on it.
