Amass of 0.01kg of steam , quality .9, is contained in
apiston-cylinder apparatus. the diameter is 20 cm and theweight of
the piston is 160kg. a linear spring, with a spring, witha spring
constant of 50kn/m, is just touching the top of thepiston. heat is
added to the system until the spring is compressed15.7 cm. what is
the final temperature?

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
