Mechanical Engineering and its specialisations
July 25, 2016

Mechanical Engineering is a branch of engineering dealing with the design, construction, and use of machines. Mechanical engineering is the discipline that applies the principles of engineeringphysics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

Here is the list of popular specialisations in the field of Mechanical Engineering:


Biomechatronics is the interdisciplinary study of biology, mechanics, electronics and control. It focuses on the research and design of assistive, therapeutic and diagnostic devices to compensate (partially) for the loss of human physiological functions or to enhance these functions.


It is the study of the mechanical laws relating to the movement or structure of living organisms.

Aerospace engineering

Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It is divided into two major and overlapping branches: aeronautical engineering and astronautical engineering


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


Robotics is the application of mechatronics to create robots, which are often used in industry to perform tasks that are dangerous, unpleasant, or repetitive. These robots may be of any shape and size, but all are preprogrammed and interact physically with the world. To create a robot, an engineer typically employs kinematics (to determine the robot’s range of motion) and mechanics (to determine the stresses within the robot).

Robots are used extensively in industrial engineering. They allow businesses to save money on labor, perform tasks that are either too dangerous or too precise for humans to perform them economically, and to ensure better quality. Many companies employ assembly lines of robots,especially in Automotive Industries and some factories are so robotized that they can run by themselves. Outside the factory, robots have been employed in bomb disposal, space exploration, and many other fields. Robots are also sold for various residential applications, from recreation to domestic applications

Acoustical Engineering

Acoustical engineering is one of many other sub disciplines of mechanical engineering and is the application of acoustics. Acoustical engineering is the study of Sound and Vibration. These engineers work effectively to reduce noise pollution in mechanical devices and in buildings by soundproofing or removing sources of unwanted noise. The study of acoustics can range from designing a more efficient hearing aid, microphone, headphone, or recording studio to enhancing the sound quality of an orchestra hall. Acoustical engineering also deals with the vibration of different mechanical systems.

Biomechanical Engineering

Biomechanics is the application of mechanical principles to biological systems, such as humansanimalsplantsorgans, and cells. Biomechanics also aids in creating prosthetic limbs and artificial organs for humans

A typical biomechanical engineering program concentrates on parts like musculoskeletal biomechanics, neuromuscular biomechanics, cardiovascular biomechanics, and rehabilitation engineering. Research in other areas including hearing, ocean, plant, and vision biomechanics exists in collaboration with associated faculty in biology, engineering, and medicine. Students will have to apply all the concepts of mechanical engineering to analyse situations related to humans and other living beings. Biomedical systems design involves designing machines for medical purposes; it is an intersection of medicine, mechanical engineering and electronics.

Materials Science & Manufacturing

In this course a mechanical engineer studies various aspects of a particular material in-depth to suggest usage and applications. Major work is involved with applying concepts of mechanics, stress and fatigue analysis to all the materials. Thermodynamics, phase transformations all play an important role in the study of materials. The field of nanomaterials is an upcoming one and is covered by many renowned universities in their programs. Understanding the process of manufacturing these materials and the optimization of the processes is another aspect of the program.

Thermal Sciences

A major in thermal engineering will include further emphasis on traditional concepts of heat transfer, fluid mechanics, radiation theory, thermodynamics, gas dynamics and combustion process fundamentals. Modern applications like space rocket propulsion, bio-analytical systems, material processing and electronics fabrication and cooling. There may be courses related to pure physics like optics and laser physics, but this varies from one university to another.


Automotive Engineering

This course will teach you to understand the working of man’s favourite toy. The various aspects of a car like chassis, suspension, engine, transmission, automotive electrical, etc. are covered in a great detail. Finding flaws, testing, quality control and innovative designing will be the major aspect of the  study of every course.

Industrial Engineering

Industrial engineering deals with the optimization of complex processes, systems or organizations. Industrial engineers work to eliminate waste of time, money, materials, man-hours, machine time, energy and other resources that do not generate value.
