2) One arm of a Wheatstone bridge is a 50 k2 strain gauge (S = 2.0). This strain gauge is bonded to a metal fixture for tensile loading, and the metal has a Young's Modulus E-2.5 MPa. The other 3 arms are fixed 50 kO resistors. The bridge is powered by 5Vv DC as shown, and Eo is the output voltage. a) Derive a relationship for Eo as a function of tensile stress o in the metal substrate, ΔL ....

Hi could you please provide how to do problem 2?
Amsterdam University of Applied Sciences Problem 2(15 points) A Wheatstone bridge is used to determine the resistance of a strain gauge. The 3 resistances R of the Wheatstone bridge are equal: R 200 12. When the strain gauge is fully relaxed (nd strain present), its resistance Rs is equal to the other 3 resistances: Rs-R. The strain is given bywith AR, the change in resistance in the strain gauge. The...
