problem1) Masses of blocks A, B, C, and D are 9 kg, 9 kg, 6 kg and 7 kg, respectively. Knowing that a downward force of magnitude 120 N is applied to block D, find out:

a) the acceleration of each block,

b) the tension in cord ABC.

Neglect weights of the pulleys and the effect of friction.

problem2) 3.0 kg of water vapor at 10 bar and 300°C is contained in a piston-cylinder device which maintains constant pressure. It is cooled until volume contained in the cylinder is .45m3. Determine the temperature of the end state? (degC)

problem3) A piston-cylinder contains 0.1kg of superheated steam at 180 degrees celsius and 5 bars. The pison is frictionless and freely floating. Heat is added until final volume is twice the initial volume.

a) What is the final temperature and change in internal energy for the steam?

b) What is the work done on or by the steam?

c) How much heat is supplied to steam?
