Description: | 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 introduce French notation and methods for problem solving by reviewing the content of year 1 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. * Formulate, solve and discuss simple solid mechanics problems in the French language. 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 Solid Mechanics 1 & 2 in French. Solid mechanics laboratory experiment. |
