A simply supported wood beam with overhang is subjected to uniformly distributed load 250 mm. q. The beam has a rectangular cross section with width b 200 mm and height h Determine the maximum permissible value q if the allowable bending stress is σ、-11 MPa, and the allowable shear stress is τ 1.2 MPa.

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.
