| Description:
| Aims: The aims of this unit are to: * analyse the three dimensional loading of selected bodies introduce slope and deflection in beams; * investigate power transmission systems; * analyse dynamic rotating systems. Learning Outcomes: By the end of the unit students should be able to: * apply analytical methods of stress analysis to selected 3D bodies and materials; * determine the slope and deflection of simply supported beams and cantilevers; * determine the power and torque transmitted by belt drives, gear trains and friction clutches; * determine the effects of coupling rotating systems and investigate the performance of flywheels. Skills: During this unit students should gain the following skills: Intellectual * gathering, processing and analysing technical information (A) * formulating outcomes (A) Professional * using information technology effectively (F,A) * determining appropriate parameters in the design of a power transmission system (F,A) Practical * developing identification and observational skills to maintain records and contribute to reports (T,A) * carrying out practical investigations of mechanical systems (F,A) Key * writing reports (A) * problem solving (T,A) * applying numerical techniques to the solution of engineering problems (T,A) * using graphs and tables to present experimental results (F,A) Content: This unit concentrates on: * identifying the relationship between longitudinal and transverse strain for cuboids and cylinders; * determining the dimensional effects of two and three dimensional loading on a variety of materials; * investigating the relationship between bending moment, slope and deflection for loaded beams and cantilevers; * determining the slope and deflection for beams and cantilevers subjected to point and uniform loads; * determining the torque and power transmitted by a belt drive system for varying pulley size and design; * investigating the performance of simple, compound and epicyclic gear trains; * determining the power transmitted by flat and cone friction clutches; * determining the power requirements of flywheels in terms of energy, angular momentum and speed/energy coefficients; * determining the energy lost due to coupling flywheels in terms of angular velocity and momentum. |
