Mechanical engineering plays a dominant role in enhancing safety, economic vitality, enjoyment and overall quality of life throughout the world. Mechanical engineers are concerned with the principles of force, energy and motion. Mechanical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices (e.g. microscale sensors and inkjet printer nozzles) to large systems (e.g. spacecraft and machine tools).
The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed. Since these skills are required for virtually everything that is made, mechanical engineering is perhaps the broadest and most diverse of engineering disciplines.

Thermodynamics is a very important branch of science and engineering that studies the role of heat and its relation to energy and work. This course introduces you to the core concepts of thermodynamics such as the relationship between pressure, volume, and temperature and how changes in one can affect the others. You will also look at examples and solve certain problems in order to help you better understand the concept of thermodynamics.
