A picture is taken of a man performing a polevault at the moment that the pole is bent the most(i. e. at the minimum radius of curvature), mea-sured to have a radius of curvature at this mo-ment of= 4:5m. If the pole has a diameterof40mm and hasE= 131GPa, determine themaximum bending stressmaxin the pole

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.
