A disk with outer radius ro = 150 mm and inner radius ri = 25 mm is press-fitted onto a shaft of radius 25.075 mm. Both members are steel with Young’s modulus, E = 205 GPa, Poisson’s ratio, ? = 0.29, and density, ? = 7845 kg·m-3. Determine and plot the radial and tangential stress distributions in the disk and shaft when it is rotating at 5000 rpm. Under the above conditions, what is the magnitude of the Von Mises stress at r = 100 mm?
