Consider the following base and derived class declarations: class baseclass { public: void basealpha(); private: void basebeta(); float basefield; }; class derivedclass : public baseclass { public: void derivedalpha(); void derivedbeta(); private: int derivedfield; }; for each class, do the following: list all private data members.

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.
