3. Determine the intensity of shear of an oil having viscosity =1 poise. The oil is used for lubricating the clearance between a shaft of diameter 10cm and its journal bearing. The clearance is 1.5 mm and the shaft rotates at 150 r.p.m
Given:
Diameter of shaft
Distance between shaft and journal bearing
Speed of shaft
Tangential speed of shaft is given by
Change of velocity between shaft and bearing
Mathematically
