Which step in the engineering design process likely broke down in the following scenario? The Tacoma narrows project required a bridge to be build over the Colombia river. the engineers accounted for aesthetic design by building a light roadbed. Unfortunately, the cables were not designed to withstand high wind speeds, and the bridge collapsed

A. Brainstorm possible solutions
B. Conduct background information
C. Design and build a prototype
D. Test and resign a prototype

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.
