Cylindrical velocity
WebL=0.5m. Bearing Shaft Lubricant P. A 25mm-diameter shaft is pulled through a cylindrical bearing as shown in the figure. The lubricant that fills the 0.3mm gap between the shaft and bearing is an oil having a kinematic viscosity of 8x10 m²/s and a specific gravity of 0.91. Determine the force P required to pull the shaft at a velocity of 3m/s. http://www.ims.cuhk.edu.hk/publications/reports/2024-01.pdf

Letting p → = x i ^ + y j ^ be the position vector, and noting that x = r cos θ, y = r sin θ, we have p → = r cos θ i ^ + r sin θ j ^ .
Web1 day ago · On a daily basis we stir tee or coffee with a spoon and leave it to rest. We know empirically the larger the stickiness, viscosity, of the fluid, more rapidly its velocity slows down. It is surprising, therefore, that the variation has not been utilized for measuring (dynamic) viscosity of fluids.
