a-journal-bearing-consists-of-a-shaft-of-diameter-d35-mathrmmm-and-length-i_050-mathrmmm-moment-of-i

A journal bearing consists of a shaft of diameter $D=35$ $\mathrm{mm}$ and length $I_{0}=50 \mathrm{mm}$ (moment of inertia $I=0.125$ $\left.\mathrm{kg} \cdot \mathrm{m}^{2}\right)$ installed symmetrically in a stationary housing such that the annular gap is $\delta=1 \mathrm{mm}$. The fluid in the gap has viscosity $\mu=0.1 \mathrm{N} \cdot \mathrm{s} / \mathrm{m}^{2}$. If the shaft is given an initial angular velocity of $\omega=500 \mathrm{rpm},$ determine the time for the shaft to slow to $100 \mathrm{rpm} .$ On another day, an unknown fluid is tested in the same way, but takes 10 minutes to slow from 500 to $100 \mathrm{rpm} .$ What is its viscosity?

A shaft 80 mm in diameter is being pushed through a bearing sleeve 80.2 mm in diameter and 0.3 m long. The clearance, assumed to be uniform, is flooded with lubricating oil of viscosity 0.1 kg/ms. (a) If the shaft moves axially at 0.8 m/s, estimate the resistance force exerted by the oil on the shaft. (b) If the shaft is axially fixed and rotated at 1800 rpm, estimate the resisting torque exerted by the oil and the power required to rotate the shaft.
