Reference no: EM13302367

A 25-mm-diameter shaft .5 m long is pulled through a cylindrical bearing. The lubricant that fills the 0.3-mm gap between the shaft and bearing is an oil having a kinematic viscosity of 8.0 × 10-4 m2/s and a specific gravity of 0.91. Determine the torque required to rotate the cylinder at a rotational speed of 70 rpm.
