Welcome! I am Md. Yeasin Bhuiyan working as a lecturer of Mechanical Engineering Department at Bangladesh University of Engineering and Technology (BUET). I completed my graduation from ME department, BUET on February, 2011.
Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. In ancient Greece, the works of Archimedes (287 BC to 212 BC) deeply influenced mechanics in the Western tradition and Heron of Alexandria (ancient Greek mathematician and engineer, 10 to 70 AD) created the first steam engine.Mechanical engineers design and develop everything you think of as a machine - from a small needle to supersonic fighter jets. Many mechanical engineers specialize in areas such as Aeronautical, Manufacturing, Robotics, Automobiles, and Air Conditioning. Others cross over into other disciplines, working on everything from artificial organs to the expanding field of nanotechnology. And some use their mechanical engineering degree as preparation for the practice of medicine and law. The mechanical engineer may design a component, a machine, a system or a process. Mechanical engineers will analyze their design using the principles of motion, energy, and force to insure the product functions safely, efficiently, reliably, and can be manufactured at a competitive cost.
Mechanical engineers work in the automotive, aerospace, chemical, computer, communication, paper, and power generation industries. Mechanical engineers will be found in virtually any manufacturing industry. Increasingly, mechanical engineers are needed in the environmental and bio-medical fields. Indeed virtually every product or service in modern life has probably been touched in some way by a mechanical engineer.
