Mechanical engineering is the engineering discipline that deals with the design, analysis, manufacture and operation of machines. Mechanical engineers are professionals who specialize in areas such as energy conversion, mechanical power and control of motion, materials science, thermal sciences, fluid mechanics, automation and manufacturing technologies.

Mechanical engineering has a wide range of applications and deals with the design and development of machines used in many industrial sectors. Below are some examples:

Machine Design: The functional, reliable and optimized design of machines. This process involves engineers working on part geometry, material selection, assembly methods, and performance analysis using drawings, modeling, and simulations.

Thermal and Fluid Mechanics: It deals with heat transfer, energy efficiency, fluid behavior and analysis of thermal systems. Mechanical engineers perform the design and analysis of thermal and fluid systems such as heating, cooling, ventilation, power generation and turbines.

Materials Science and Strength: Works on durability, strength and material selection of machine parts. Materials science involves understanding the mechanical properties and behavior of different materials and optimizing material selection.

Automation and Control Systems: It deals with automation of machines, control systems and robotic technologies. This area includes the design of automation systems, the use of sensors and actuators, data analysis and the development of control algorithms.

Production Technologies: Mechanical engineers work on improving production processes, designing production lines, quality control methods, and production efficiency. Working with engineers specializing in manufacturing engineering and production management, they create effective production processes and facilities.

Mechanical engineering is a multidisciplinary field that requires skills to analyze, design, test, improve and manage complex problems.
