A440c stainless steel alloy has the following properties: density 0.28 lb/in^3, elastic modulus 29 mpsi, yield strength 275 ksi, and work hardening exponent 0.04. what would be the ultimate tensile strength (find both nominal and true)? (hint: use sigma y as sigma nom, and find total strain (true and nominal))

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
