How Does it Work?

EIT eLearning courses involve a combination of live, interactive sessions over the Internet with a professional instructor, set readings, and assignments. The courses include simulation software and remote laboratory applications to let you put theory to practice, and provide you with constant support from a dedicated Course Coordinator.

Practical Exercises and Remote Laboratories

As part of the groundbreaking new way of teaching, our online engineering courses use a series of remote laboratories (labs) and simulation software, to facilitate your learning and to test the knowledge you gain during your course. These involve complete working labs set up at various locations of the world into which you will be able to log to and proceed through the various practical sessions.

These will be supplemented by simulation software, running either remotely or on your computer, to ensure you gain the requisite hands-on experience. No one can learn much solely from lectures, the labs and simulation software are designed to increase the absorption of the materials and to give you a practical orientation of the learning experience. All this will give you a solid, practical exposure to the key principles covered and will ensure that you obtain maximum benefit from your course.

Courses available in EIT's School of Mechanical Engineering

Mechanical Engineering encompasses the conceptualization, design, manufacture, control and maintenance of machines ranging from a conveyer, space shuttle to nanotechnology based objects. In broad terms, mechanical engineering channels the energy and forces in nature to the service of people. The fields in which mechanical engineering professionals operate are wide - ranging from oil and gas, power generation, water utilities, process plants, mining, pharmaceuticals, manufacturing and defence.

A diploma in mechanical engineering is ideal for anyone wanting to get involved in the general engineering (whether design or maintenance) of large plants, especially as a plant engineer. Recently, mechanical engineering has begun to include many new systems in the electronics and control arena such as programmable logic controllers (PLCs) and SCADA as these are critical to the control of mechanical devices.

Students in the Engineering Institute of Technology (EIT) School of Mechanical Engineering can study an Advanced Diploma of Mechanical Engineering with subjects that include: mechanics, structural engineering, drive systems, rotating equipment, hydraulics, pneumatics, lubrication engineering, HVAC, pumps, compressors, machinery safety, energy efficiency and renewable energy sources. The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology.

The focus in EIT's School of Mechanical Engineering is in providing students with both deep and broad skills in mechanical engineering technology, focusing on real systems. Whilst there is probably not a shortage of theoretically orientated practitioners in mechanical engineering, there is a need for highly skilled, practically oriented engineers, technologists and technicians, due to the rapidly increasing use of new technologies which are becoming a key component of all modern plants and equipment. Studying our mechanical engineering courses online means you do not have to take extended periods away from existing work commitments.
