A shaft 12.5 mm diameter rotates in long bearings and a disc of mass 16 kg is secured to a shaft at
the middle of its length. The span of the shaft between the bearing is 0.5 m. The mass centre of the
disc is 0.5 mm from the axis of the shaft. Neglecting the mass of the shaft and taking E = 200
GN/m2, find : 1 critical speed of rotation in r.p.m., and 2. the range of speed over which the stress
in the shaft due to bending will not exceed 120 MN/m2. Take the static deflection of the shaft for a
beam fixed at both ends, i.e.
