A torsional system consists of a mass moment of inertia disk of 30 kg.m? and a torsional damper with damping of 300 Nms/rad and a steel shaft (G=80Mpa) of 5 cm outer diameter, inner diameter of 2 cm and 1.5 m long. The shaft is crimped at one end and the disc is installed at the other. An angular oscillation of 4° amplitude is observed when a harmonic torque of magnitude of 2000 N.m is applied to the disk. Determine the maximum torque transmitted to the support in N.m.

Please give step wise solution

A torsional system consists of a mass
moment of inertia disk of 30 kg.m? and a
torsional damper with damping of 300
Nms/rad and a steel shaft (G=80Mpa) of 5
cm outer diameter, inner diameter of 2 cm
and 1.5 m long. The shaft is crimped at one
end and the disc is installed at the other. An
angular oscillation of 4° amplitude is
observed when a harmonic torque of
magnitude of 2000 N.m is applied to the
disk. Determine the maximum torque
transmitted to the support in N.m.
