Aims:
* To introduce the vibrations of mechanical systems in a one degree of freedom context. * To introduce the theory of torsion in non-circular and open- sections, dual axis bending and the concept of fatigue failure. * To review the content of the first year Solid Mechanics units in the French language. Learning Outcomes: After taking this unit the student should be able to: * Set up the equations of motion for systems with one degree of freedom; find natural frequencies of free motion; calculate rates of decay from viscous damping and vice versa; determine motions resulting from a sinusoidal force, unbalance and base excitation. * Estimate maximum responses using shock spectra. * Calculate shaft critical speeds. * Calculate torsional stiffness and strength values for closed and open structural sections. * Predict bending stresses in dual axis bending. * Predict the fatigue life of some simple structural forms based on S-N calculations. Skills: Problem solving; numeracy; working independently; communicating in the French language. Content: One degree of freedom systems: free and forced vibration; base excited motion; unbalance excitation; vibration isolation. Torsion of open and closed structural sections, dual axis bending. Stress concentration, fatigue strength and cumulative damage in structural components. Review of structural mechanics in French. Solid mechanics laboratory experiment. |
