The following data relate a shaft held in long to bearings. - 1.2 m Length of shaft Diameter of shaft Mass of a rotor at midpoint Eccentricity of centre of mass of rotor from centre of rotor Modulus of elasticity of shaft muterial Permissible stress 14 m 16 kg 0.4 mm - 200 GN/m - 70 x 10* N/m in shaft material Determine the critical speedof the shaft and the range of speed over which it is unsafe to run the shaft. Assume the shaft to be massless.
