explain the phenomena of ship and shaft vibrations, modes, causes, effects, and attenuation procedures
distinguish between torsional and lateral vibrations, free and forced vibration of single- degree and multi-degree of freedom systems
calculate vibration parameters such as inertia, damping and stiffness coefficients; natural frequency, magnification, log decrement, etc
apply both numerical and analytical methods for analysing multi-degree of freedom shafts;
utilise vibration measuring instruments for measuring vibration modes, amplitude, frequency, phase angle and critical speed.
