Consider shear panels with uniform thickness of 5 mm made of aluminum alloy with E = 70GPa, and ν = 0.33. Assume simply supported boundary conditions on all edges. One panel is flat while the other panel comprises the same amount of material but is bent into a cylindrical shape.

a) If the panels are loaded with uniform shear along their edges, determine the buckling stress τcr for each of the two panels. Use the charts included on the last page of this assignment for the curved panel case.

b) If the panels are loaded with uniform normal stress along the shorter end, as shown, determine the buckling stress σcr for each of the two panels. Also, for the case of the flat panel, make a sketch illustrating the buckling mode that you expect. [Note: for the curved panel case, look up an appropriate formula/data from "Roark’s Formulas for Stress and Strain.

c) Compare all results and comment.

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.
