A hollow steel shaft of outer diameter (50 mathrm{~mm}), inner diameter (38 mathrm{~mm}), and length (750 mathrm{~mm})

Question:

A hollow steel shaft of outer diameter \(50 \mathrm{~mm}\), inner diameter \(38 \mathrm{~mm}\), and length \(750 \mathrm{~mm}\) carries a solid disc of diameter \(380 \mathrm{~mm}\) and mass \(40 \mathrm{~kg}\). Another hollow steel shaft of length \(500 \mathrm{~mm}\), carrying a solid disc of diameter \(150 \mathrm{~mm}\) and mass \(8 \mathrm{~kg}\), is attached to the first disc, as shown in Fig. 9.52. Find the inner and outer diameters of the shaft such that the attached shaft-disc system acts as an absorber.
