(a) A 3 mm thick turbine disc with 100 cm diameter and a bore
diameter of 2 cm has an angular velocity of 1500 rpm. The disc is
made of material with density of 8000 kg/m3 and Poisson’s ratio of
0.25. Determine the followings:
i) Location and magnitude of maximum radial stress of the turbine
disc.
ii) Magnitude of maximum and minimum hoop stresses of the
turbine disc.
