Introduction To Mechanical Engineering

Mechanical engineering, a branch of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems and involves in the production and usage of heat. It also applies to mechanical power for the design, production, and operation of machines and tools. It is the oldest and broadest engineering disciplines.

The engineering stream requires a vast understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, and structural analysis. Mechanical engineers are made use these core principles along with tools like computer-aided engineering and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, motorized vehicles, aircraft, watercraft, robotics, medical devices and more.

Mechanical engineering was brought to light as during the industrial revolution in Europe in the 19th century however, its development can be traced back several thousand years around the world. The field is continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as composites, mechatronics, and nanotechnology. Mechanical engineering coincides with aerospace engineering, civil engineering, electrical engineering, and petroleum engineering to varying amounts.

Fields That Come Under Mechnical:

Nanotechnology:

At the smallest scale, mechanical engineering becomes nanotechnology —one speculative goal of which is to create a molecular assembler to build molecules and materials via mechanosynthesis.

Mechatronics:

Mechatronics is a synergistic combination of mechanical engineering, electronic engineering, and software engineering. This engineering field is the study of automation from an engineering perspective and serves the purposes of controlling advanced hybrid systems.

Finite element analysis:

This is not a new field, as the basis of Finite Element Analysis (FEA) or Finite Element Method (FEM) dates back to 1941. But the evolution of the computers has made FEM a viable option for analysis of structural problems. Other techniques that are, finite difference method (FDM) and finite-volume method (FVM) are employed to solve problems relating heat and mass transfer, fluid flows, fluid surface interaction etc.
