Technician a says during the manufacturing of a wheel cylinder, the cylinder bore or inside diameter is created by drawing a properly sized ball bearing through the bore, which gives the surface a hard, smooth finish. technician b states that most manufactures recommend replacing rather than honing the wheel cylinder if it has pits or corrosion. who is correct?

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.
