Design of mechanical systems
Mechanical engineering is the design, production and use of mechanical systems that control and transform energy.
As a student in mechanical engineering, you will be trained in
- statics, dynamics and vibrations,
- heat transfer and fluid mechanics,
- solid mechanics and biomechanics,
- controls and mechatronics,
- materials science,
- analysis and synthesis of mechanical systems, and
- ME 215: Fluid Mechanics I
The basic principles of fluid mechanics are introduced. A generalised approach to fluid statics is used as an introduction to calculating the forces exerted by fluids on surfaces. Fluid dynamics is approached using a control volume formulation and basic pipe flow is introduced. Potential flow is applied to calculate the velocity and pressure fields over basic shapes.
- ME 314: Machine Design I
Deals with various machine design fundamentals and the use of integrated design software. Design for fatigue and consideration of fracture mechanics is emphasized. Topics include: the selection of fasteners, rolling element bearings, V-belts and roller chains and the design of coil and leaf springs, spur gears, clutches and brakes.
- ME 471: Introduction to Aerodynamics
This course is an introduction to aerodynamics which explores the lift and drag performance of airfoils. Potential flow is used to develop the theory of flow over airfoils and wings, using both classical and numerical - e.g. vortex panel - methods. Boundary layer theory is used to explain the role of viscosity and the potential flow of seperation. Numerical models are used to predict skin friction values. Finally, the development of shock waves for supersonic conditions is considered.
The mechanical engineering profession offers a wide variety of career paths, including opportunities in the following:
- designing and manufacturing vehicles, from automobiles to spacecraft
- designing and developing advanced renewable energy systems like wind turbines and solar collectors
- designing mechanical devices for biomedical applications
- working in all aspects of the energy supply and delivery systems: power generation, pipelines, and petroleum production
- designing heating, ventilating, air conditioning and building envelopes for efficient energy use
- designing and controlling robotic systems
Today’s mechanical engineers typically work in large multi-disciplinary teams. As skilled problem-solvers, they combine an in-depth understanding of physics, chemistry and mathematics with applied engineering science and the art of design.
