Apipe with closed ends has a wall thickness of 10 mm and an inner diameter of 0.60 m. it filled with a gas at 20 mpa pressure and subjected to a torque about its long axis of 1200 kn·m. a. determine the three principal normal stresses and the maximum shear stress. recall from basic mechanics that: = t / b. if the pipe is constructed of oil-quenched and tempered 4340 steel with a yield strength of 1620 mpa, what is the safety factor against yielding using the tresca maximum shear stress criterion? c. prior to loading, an inside crack is discovered through 25% of the thickness of the sample. with this crack, what is the safety factor against fracture if the plane strain fracture toughness is 87.4mpa√m?

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.
