Mechanical Engineering is most often associated with machines that move, from motorcycles and Formula 1 cars to aircraft and ships. However, virtually all man-made products have mechanical features that are designed and developed by mechanical engineers. Hence, companies that make such diverse products as mobile phones, shoes, artificial hip joints, musical instruments and tennis rackets employ mechanical engineers. In all cases, they are employed to apply the scientific knowledge, design expertise and problem-solving skills they have acquired at university. Queen's School of Mechanical and Aerospace Engineering has an international reputation for its contributions to the development of engineering education. For example, it is currently playing a leading role in the CDIO initiative to enhance engineering education, involving universities from around the world.
