What is Mechanical Engineering?

Mechanical Engineering plays a vital role in shaping our world. It stands as one of the oldest engineering professions, with its roots dating back to the Industrial Revolution in the 18th and 19th centuries. James Watt’s invention of the steam engine in 1802 propelled the field’s rapid growth. With the advent of the automobile, there arose a need for precisely machined metal components and a more formalized assembly process.

Involving the design, construction, and improvement of man-made devices, Mechanical Engineering encompasses a wide range of areas, including machines, power systems, production lines, boilers, pressure vessels, and automobiles. It is the second-largest engineering profession, surpassed only by Electrical Engineering.

Job For Mechanical Engineers

The Job Traditionally, Mechanical Engineers would calculate equipment dimensions at drafting tables while machine shops fabricated the parts. Today, much of the design work is accomplished using Computer-Aided Design (CAD) programs. The future envisions developing designs on computers, testing them with specialized software, and then sending the designs to automated production machinery for fabrication and assembly.

Mechanical Engineers work in various fields, including:

  • Basic Engineering: Fluids, applied mechanics, heat transfer, tribology (the study of lubrication), and bioengineering.
  • General Engineering: Management, safety, and technology and society.
  • Manufacturing: Materials handling, production engineering, textile engineering, process industries, and plant engineering and maintenance.
  • Energy Conversion: Fuels and combustion technologies, internal combustion engines, power and nuclear engineering.
  • Materials and Structures: Materials, pressure vessels and piping, offshore mechanics, and Arctic Engineering.
  • Energy Resources: Petroleum, solar energy, ocean engineering, and advanced energy systems.
  • Environment and Transportation: Rail, aerospace, environmental control, solid waste processing, noise control, and acoustics.

Some typical job titles in Mechanical Engineering include:

  • Design Engineer: Developing new machinery or components through computer programs, laboratory models, and prototypes.
  • Manufacturing/Production Engineer: Ensuring smooth operation of production lines, power plants, and assembly processes by coordinating various stages of the manufacturing process.
  • Maintenance Engineer: Restoring faulty machines to working condition while analyzing the root causes of failures.
  • Reliability and Testing Engineer: Developing testing methods and reviewing processes to assess the durability and performance of equipment.

Education in Mechanical Engineers
