Mechanical engineering applies the principles of physics and engineering science to the analysis, design and maintenance of mechanical systems. It defines how and why mechanical systems work, how long they will work for and predict when they will fail.Mechanical Engineers are at the heart of a broad spectrum of UK and international industrial sectors. They design and specify products ranging from heart stents to bullet trains, and work extensively in a large range of differing industrial sectors.Covering an extensive range of disciplines from dynamics and control, to stress analysis heat transfer and thermodynamics, a diverse array of engineering science-based subjects are experienced, providing technical expertise and integration of skill sets. Mechanical engineering takes advantage of parallel engineering disciplines, blending subjects such as materials science, electronics and software engineering with the core subjects.
