Considering the two portal frames below, each with an applied lateral load of 10k, assume the beam and column EI to be the same. Often in design, the building code maximum displacement limit controls the lateral force resisting system design. If the maximum allowed displacement for this load is 2% of the column height, what is the minimum required EI for each frame assuming the frame beam length?

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.
