Aset of objects (a "collection") can be implemented as an extension of an unordered list class. in addition to the existing operations for insertion, deletion and scanning elements, the "listset" class would need operations for unionwith( ), intersectwith( ), and subtract( ) methods.

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.
