## Find the minimum film thickness for a bearing with these data: 30-mm dia, 25 mm long, 0.0015 clearance ratio, 1 500 rpm, ON = 30, ISO VG 220 oil at 200°F.

1.       Problem 7-12 estimated the volume of adhesive wear to expect from a steel shaft of 40 mm dia rotating at 250 rpm for 10 years in a plain bronze bushing with a transverse load of 1 000 N for conditions of both poor and good lubrication. If the bushing has l / d = 0.5 and a clearance ratio of 0.001, define the lubricant viscosity in microreyn (μreyn) needed to obtain good lubrication.
