Determine the true stress and true strain at failure
A copper wire of diameter 0.80 mm fails at an engineering stress = 248.2 MPa. Its ductility is measured as 75% reduction of area. Determine the true stress and true strain at failure.

Liquid octane (C8H18) at 25ºC, 1.0 atm enters a well-insulated reactor and reacts with air entering at the same temperature and pressure.
Water flows straight down from an open faucet. The cross-sectional area of the faucet is 1.2 × 10-4m2 and the speed of the water is 0.55 m/s as it leaves the faucet. Ignoring air resistance, find the cross-sectional area of the water stream
Determine the yield strength, modulus of elasticity, tensile strength, and percent elongation. Also determine the strength coefficient and the strain-hardening exponent in the flow curve equation.
A piping system consists of 100 ft of 2-in pipe, a sudden expansion to 3-in pipe, and then 50 ft of 3-in pipe. Water is flowing at 100 gal/min through the system. What is the pressure difference from one end of the pipe to the other?
