Two strain gauges are mounted so that they sense axial strain on a steel member in uniaxial tension. The 120 Ω gauges form two legs of a Wheatstone bridge, and are mounted on opposite arms (e. g., arms 1 and 4). The gauge factor for each of the strain gauges is 2 and Em for this steel is 29 × 106 psi. For a bridge excitation voltage of 4 V and a bridge output voltage of 120 μV under load (i. e., Ei = 4 V and 0 E =120 μV ):
