Consider a 40-cm-long journal bearing that is lubricated with oil whose viscosity is $0.1 \mathrm{~kg} / \mathrm{m} \cdot \mathrm{s}$ at $20^{\circ} \mathrm{C}$ at the beginning of operation and $0.008 \mathrm{~kg} / \mathrm{m} \cdot \mathrm{s}$ at the anticipated steady operating temperature of $80^{\circ} \mathrm{C}$. The diameter of the shaft is $8 \mathrm{~cm}$, and the average gap between the shaft and the journal is $0.08 \mathrm{~cm}$.Calculate the torque needed to overcome the bearing friction initially and during steady operation when the shaft is rotated at $800\ \mathrm{rpm}$.
