1. a strip of high strength steel has a length of 30 cm and a cross section of 1 mm x 20 mm. the modulus of elasticity is 200 gpa, and poisson’s ratio is 0.27. it is subjected to an axial load of 15000 n, and it is instrumented with two axial strain gages, with r=120 ohms and a gage factor of 2.10. the two gages are connected into opposite legs of a wheatstone bridge (r1 and r3). the two fixed resistors are also 120 ohms, and the supply voltage is 2.5 v. the bridge is adjusted to zero voltage output before the load is applied. find the output of the bridge with the load applied.
