The moment of inertia of the driven shaft in a Hooke's joint is \(35 \mathrm{~kg} . \mathrm{m}^{2}\). The driven shaft is inclined at \(30^{\circ}\) to the axis of the driving shaft. The driving shaft rotates at \(2700 \mathrm{rpm}\) with a steady torque of 275 N.m. Determine the maximum fluctuation of output torque.
