Engineering is a discipline that uses mathematics and science to solve problems in building, testing and designing structures, machines and processes. An Engineer would design the infrastructure; devices that we use and they assembled and managed by an engineer as well. Our surrounding is built by an engineer in every way in this modern world of technology. The human needs that make our lives easy in day to day world basically the machines we use to make our lives easy and comfortable from a small battery to an airplane.

There are various disciplines in Engineering which includes Mechanical, Civil, Electronic, and Chemical. Mechanical Engineering is one of the major disciplines in creating machines and managing machines to meet the human needs.

It can be found that Mechanical Engineering has its roots during the Industrial Revolution in the 18th Century and the requirement of innovative and sophisticated engineering solutions led to its development which will help in the advent of the steam engine, automated manufacturing, and the demands of railroad transportation. The developments in physics in the 19th Century led the developments in Mechanical Engineering sciences. The discipline has been evolving and incorporating much advancement in human needs; it has also

developing other areas like composites, mechatronics, and nanotechnology.

This branch combines engineering physics and mathematics principles with materials science, and then it develops design and analyzes to manufacture, and maintain mechanical systems. The field is acknowledged as one of the oldest and broadest of the engineering discipline. The branch has some core areas which include mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity.

To resolve some problems Mechanical Engineering includes some other disciplines but they are not limited to this process, they are used in some way to make the process or design more favorable and strong. That are-

  • Acoustics
  • Aerospace
  • Automation
  • Automotive
  • Autonomous Systems
  • Biotechnology
  • Composites
  • Computer Aided Design (CAD)
  • Control Systems
  • Cyber security
  • Design
  • Energy
  • Ergonomics
  • Human health
  • Manufacturing and additive manufacturing
  • Mechanics
  • Nanotechnology
  • Production planning
  • Robotics
  • Structural analysis

Scientists study the world as it is; engineers create the world that has never been.
— Theodore von Kármán

It is the branch of engineering that involves the design, production, and operation of machinery. Works of Mechanical Engineer as an Engineer, they work in offices and sometimes visit to field if the machine needs their personal attention or to supervise the construction site. Mechanical engineers work mostly in engineering services, research and development, and manufacturing. They deal with anything that moves, from components to machines to the human body.

Technically, mechanical engineering is the application of the principles and problem solving techniques of engineering from design to manufacturing to the marketplace for any object. Mechanical engineers use the principles of motion, energy, and force to evaluate their work and make sure that designs function safely, efficiently, and reliably, all at a competitive cost.

Mechanical engineers construct or design a difference in life of a human being. They create or their motive is centered on creating technologies to meet human needs; the needs that makes human life easier. Nearly every possible product or service, we use in modern life has been touched in some way by a mechanical engineer to help human world. This includes solving today’s problems and creating future solutions which will remain

in human’s life as a solution in health care, energy, transportation, world hunger, space exploration, climate change, and many more.

As mechanical engineers use many fields to solve many challenges and offers many innovations across many fields means a mechanical engineering education is inventive. To meet the human demand mechanical engineers are capable of designing a component, a machine, a system, or a process. The variety they can present from the macro to the micro, from the largest modes like cars and satellites to the smallest mechanisms like sensors and switches. The manufactured or anything with moving parts needs the skills of a mechanical engineer.

The essence of Engineering is solving problems whether it is research oriented or creating new human requirements. Those who are getting their admission in engineering they will definitely be get touched by this branch of engineering to make the world of human needs. By creating a product is only part of the equation where a mechanical engineer gets to know how to work with people, ideas, data, and economics fully.

Different from science, Engineers try to make things that do not exist in nature. On the other hand, scientists try to understand nature. Engineer works on innovating designs and inventing ideas. The engineers have to put idea in real terms and design things that humans can use while inventing anything. Even though engineers use scientific terms to invent or design anything, they also have to take into account efficiency, economy, reliability, and constructability or ease of fabrication as well as the environment and many other legal consideration for the failure of their solutions as well.
