What is Mechanical Engineering?


Mechanical engineering is the broadest of all engineering disciplines. It is central to industries as varied as healthcare, design, manufacturing, food production, power generation and transport. As a mechanical engineering graduate, you will be involved in designing, building, automating, testing and managing. Mechanical engineers have contributed to technologies that we use everyday:

Design in TU Dublin: We place a strong emphasis on design and help students to understand the design process. It is creative, exciting and challenging work, and we use the latest 3D computer aided design packages.

Material Analysis: Did your mobile phone ever drop? Did the casing crack? At TU Dublin - Tallaght Campus, our mechanical engineering students use specialised equipment to examine material properties and to calculate mechanical characteristics of parts.
Impact Forces: When you look at road safety ads on TV you sometimes see the results of the impact forces in a collision, which can cause severe injury or worse. Mechanical engineers ensure that cars and other vehicles are safer through careful design and simulation.

Machinery: The humble bicycle and moped and the less humble motor car with all their many moving parts are the domain of the mechanical engineer. The JCB with its ability to literally shift mountains puts enormous engine power and amazing hydraulics to work in moving heavy loads.

Medical Industry: Do you know somebody who has needed a hip replacement operation? Prosthetic (artificial) hips are made from a metal alloy. These medical devices have to be made to a high degree of accuracy. Mechanical engineers can use Rapid Prototyping Technology to design and configure the exact body space to be occupied by a patient’s new hip.

Manufacturing: Manufacturing products is a very big part of the engineering world. In manufacturing, the plans come straight off the computer. Material is measured, cut, formed, polished and painted by very sophisticated machines including robots. Computer aided designs (CAD) become reality. A prototype is ready for testing! AT TU Dublin this is one of our major strengths.

Manufacturing and Engineering Systems: We also help our students to get a feel for entire systems. In the future they may work on aircraft engine production, power station maintenance, water filtering plants, computer chip production systems, pharmaceutical production facilities or light rail systems. They have to consider total systems and how all the components relate to each other. So, we prepare our students for the opportunities offered in the understanding, maintenance and improvement of complete systems.
