Question 6 10 pts Consider the strain transducer below, with constant supply voltage Vi, two constant resistors with resistance R, and two strain gauges, RG, and RG2, with identical nominal resistance Rnom and gauge factor G that are differentially activated by complementary strain e , ( RG, is stretched) and -E (RG2 is compressed) as shown below. RG1 = Rnom (1 + GE) RG2 = Rnom (1 - GE) V. R -E + R RGI Which of the following correctly express output voltage V, as a function of strain E? (2) V. = GEVi (ii) Vo = GE Vi (izi) V. = 2GEV (iv) Vo = - GEVA (v) V. = -GEVA (vi) V. = -2GEV
