A pivot bearing used on the shaft of an electrical instrument is shown in the figure below. An oil with a viscosity of μ = 0.010 lb- s/ft² fills the 0.0010-in. gap between the rotating shaft and the stationary base. Determine the frictional torque on the shaft when it rotates at 3000 rpm. 0.0010ín.
