Mechanical engineering in simple terms deals with any equipment that moves; this is what makes it perhaps the most broad and diverse of engineering disciplines. The mechanical discipline essentially derives its breadth from the need to design and manufacture everything from small, even nano, individual devices, such as measuring instruments, to large systems such as machine tools and power plants. Easy installation and serviceability are critical to the success of a mechanical system as is operational and design flexibility. Understanding parameters governing the selection and design of mechanical systems is essential for identifying suitable systems for a particular application.
In order to place all these issues in context, a good working knowledge of mechanical principles combined with a solid understanding of key concepts such as force, energy and heat is important. Mechanical power transmission is discussed from the point of view of gears, couplings and bearings. Proper selection and sizing of these critical mechanical components is vital to ensuring optimum performance and improved efficiency of a mechanical system. Recently, fluid engineering has undergone significant change and therefore a detailed overview of the underlying principles of fluid power and its applications is vital. The theory behind heat transfer, the various heat transfer mechanisms and the design of heat exchangers is also examined.
Any study of mechanical systems would be incomplete without including a review of mechanical vibrations. This will help you in monitoring, controlling and analyzing vibrations and in conducting fault diagnoses in mechanical systems. The field of maintenance has evolved into a separate and highly specialized function. An effective maintenance regime helps identify failure symptoms and enables initiation of corrective measures, for preventing unscheduled and sometimes catastrophic failures. Lastly, a discussion on the numerous standards, codes and regulations governing mechanical systems, helps put the whole course into perspective.

What are the fees for my country?
The Engineering Institute of Technology (EIT) provides distance education to students located almost anywhere in the world – it is one of the very few truly global training institutes. Course fees are paid in a currency that is determined by the student’s location. A full list of fees in a currency appropriate for every country would be complex to navigate and, with today’s exchange rate fluctuations, difficult to maintain. Instead we aim to give you a rapid response regarding fees that is customised to your individual circumstances.
We understand that cost is a major consideration before a student commences study. For a rapid reply to your enquiry regarding courses fees and payment options, please enquire via the below button and we will respond within 1 business day.
Please contact us with your location for certificate fees in the relevant currency. Certificate fees include all live webinars with a professional instructor, 4 technical manuals (as searchable eBooks), course materials, software, postage, assignments and ongoing support. All you need to participate is an internet connection, computer and headset. We have group discounts available for our 3 month certificates.
Three payment options are available for the Advanced Diploma courses;
Pay total amount upfront to receive a 5% reduction in fees.
Pay in 6 equal instalments over the duration of the course. First payment at least four weeks before the course starts. Payment dates will be set ahead of time and provided at the start of the course. You would receive the 30 technical reference eBooks in batches over the duration of the course.
Pay in even monthly instalments. First payment at least four weeks before the course starts, then one on the same date every month for the remaining period. This option incurs a 2% administration fee. You would receive the 30 technical reference eBooks in batches over the duration of the course.

Mechanical Engineering encompasses the conceptualisation, 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 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 diploma online means you don't have to take extended periods away from existing work commitments.
