Question: Determine the natural frequency and position of the node for the free torsional vibrations of the stepped shaft shown in Fig.17.59. (G=80 mathrm{GPa}). -100 mm

Determine the natural frequency and position of the node for the free torsional vibrations of the stepped shaft shown in Fig.17.59. $G=80 \mathrm{GPa}$.

-100 mm -80 mm 50 mm -0.5 m- J = 600 kg.m

-100 mm -80 mm 50 mm -0.5 m- J = 600 kg.m +0.5 m- 0.5 m- J = 200 kg.m Fig.17.59 Stepped shaft
