If the static deflection is 1.665×10-3m, calculate the critical speed of the shaft in rps. Centre of disc at 0.25m away from centre of axis of shaft.

If the static deflection is 1.665×10-3m, calculate the critical speed of the shaft in rps. Centre of disc at 0.25m away from centre of axis of shaft. Correct Answer 12.2

d = 1.665×10-3m substituting these values into the frequency relation of transverse vibrations we get Nc = 12.2 rps.
