A 25 mm diameter shaft is pulled through a cylindrical bearing as shown in the figure. The lubricant that fills the 0.3 mm gap between the shaft and the bearing is an oil having a kinematic viscosity of 8.0 x 10 -4m²/s and a specific gravity of 0.91. Determine the force P required to full the shaft at a velocity of 3 m/s. Assume that the velocity distribution between the gap to be linear. Bearing Lubricant Shaft Answer: a. force P N
