A strip of high-strength steel has a length of 30 cm and cross section of 1 mm × 20 mm. The modulus of elasticity is 200 GPa, and Poisson’s ratio is 0.27. It is subjected to an axial load of 15,000 N, and it is instrumented with two axial strain gages, with R = 120 Ω and a gage factor of 2.10. These two gages are connected into opposite legs of a Wheatstone bridge (R1 and R3). The two fixed resistors are also 120 Ω, and the supply voltage is 2.5 V. The bridge is adjusted to zerovoltage output before the load is applied. Find the output of the bridge with the load applied.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
