Question:
A pivot bearing used on the shaft of an electrical instrument is shown in Fig. P1.86. An oil with a viscosity of \(\mu=0.010 \mathrm{lb} \cdot \mathrm{s} / \mathrm{ft}^{2}\) fills the \(0.001-\) in. gap between the rotating shaft and the stationary base. Determine the frictional torque on the shaft when it rotates at \(5000 \mathrm{rpm}\).
