Aims
The aim of this module is to provide students with advanced knowledge of the mechanical theories associated with engineering applications.
Topics included: Poisson’s Ratio; the relationship between the elastic constants; the relationship between bending moment, slope and deflection in beams; calculating the slope and deflection for loaded beams; analysing the stresses in thin-walled pressure vessels; and stresses in thick-walled cylinders, flat and v-section belt drive theory, operational constraints of dynamic rotating systems, friction clutches and brakes.
Learning Outcomes
1.
Determine the behavioural characteristics of materials subjected to a variety of loadings
2.
Assess the strength of loaded beams and pressurised vessels.
3.
Analyse the specifications of power transmission system elements.
4.
Examine operational constraints of dynamic rotating systems.
Module Content
Outline Syllabus:Characteristics of materials: Poisson’s Ratio, relationship between the elastic constants, characteristics of two-dimensional and three-dimensional loading, calculation of volumetric strain and volume changes
Strength: relationship between bending moment, slope and deflection in beams, stresses in thin-walled pressure vessels and in thick-walled cylinders.
Power transmission systems: flat and v-section belt drive theory, friction clutches, principles of epicyclic and differential gearing, torques required to accelerate these systems, areas of failure when transmitting power mechanically
Dynamic rotating systems: design of both radial plate and cylindrical cams to meet operating specifications, operating principles of flywheels to store mechanical energy, balancing of rotating mass systems, effects of coupling on freely rotating systems
