Acantilever of length 0.5 m and square cross-section of sides 50 mm is subjected to a downward-acting alternating end load. the static tensileield s for completely reversed stress of the material are(300 ? if the mean stress ? m-30 mpa, using the soderberg-equation. and f a. an determine the maximum and minimum values of the end load. also show stress-time variation curve (sinusoidal).

1kg of water contained in a piston-cylinder assembly undergoes two processes in series from an initial state where the pressure is 3.0 bar and the temperature is 150°c process 1-2: the water is compressed isothermally to a volume of 0.25 m^3 with 120 kj of work being done to the system. process 2-3: the water is heated at constant volume to a final pressure of 10 bar. a. find the change in internal energy for the system. b. calculate the amount of heat transferred, in kj. c. sketch both processes on a t-v diagram. (196.33 kj/kg, 76.33 kj)
