Question:
A flywheel has a moment of inertia of 50 kg m2. It is suspended on the end of a vertical shaft 2 m long and 40 mm diameter. A torsional damper is fitted with a damping ratio of 0.125. The modulus of rigidity of the shaft is 80 GPa. Calculate the following. The torsional stiffness of the shaft. (10053 N m s/radian) The critical damping coefficient for the system. (1 418 Nms/rad) The frequency of damped oscillations? (2.24 Hz). The amplitude reduction factor.
