The crankshaft-flywheel assembly of a large engine may be considered a torsion pendulum. The shaft is 1.8m long and transmit 179.127kN-m torque corresponding to 83MPa stress. The flywheel diameter is 75cm and weighs 4.5kN. If the modulus of rigidity of the shaft material is 77GPa, compute the period of vibration of this system.
