A strip of high-strength steel has a length of 30 cm and a cross section of 1 mm by 20 mm. The modulus of elasticity is 200 GPa and Poison’s ratio is 0.27. It is subjected to an axial load of 15000 N, and it is instrumented with two axial strain gauges with R= 120 Ω and a gauge factor of 2.10. The two fixed resistors are also 120 Ω, and the supply voltage is 2.5 V. The bridge is adjusted to zero voltage output before load is applied. Find the output of the bridge with load applied.
