Q1) The strain measurement device uses the circuit shown in Figure 1. The strain gauges G1 and G2both have (10000) and gauge factor (2). The feedback resistance between the node A and B should be70kn. Compute the output voltage at node B when the strain at G1 have the following values (50, 100,250, 400, 60) ɛ and plot the computed voltage against the strain.6.79Balance100k22%Gain10kG247KFigure 122%100800100EAnalogueoutputOv
