If each of the parameters \((\mu, R, l, d\), and \(N\) ) of the journal bearing described in Problem 1.66 is subjected to a \(\pm 5 \%\) variation about the corresponding value given, determine the percentage fluctuation in the values of the torsional damping constant and the damping torque developed.

Data From Problem 1.66:-

Find the torsional damping constant of a journal bearing for the following data: Viscosity of the lubricant \((\mu): 0.35\) Pa-s, Diameter of the journal or shaft \((2 R): 0.05\mathrm{~m}\), Length of the bearing \((l): 0.075\mathrm{~m}\), Bearing clearance \((d): 0.005\mathrm{~m}\). If the journal rotates at a speed \((N)\) of \(3000 \mathrm{rpm}\), determine the damping torque developed.
