A 5" x 5" plate is loaded with normal stress x and shearing stress xy, and constrained so that x (0,0) = y (0,0) = 0 and y (5,0) = 0. The plate is 0.25" thick, with = 10 and = 0.3. Assume plane stress, and assume the stress and strains are constant in the plate. Point A, located at (4,3) displaces 0.01356" in the x-direction and -0.0027" in the y-direction. What is the total strain energy?

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
