Mechanical Engineering: Introduction

Mechanical Engineering is one of the oldest branches of Engineering. It is one of the core branches. Though this discipline has existed for a very long time, Mechanical Engineering developed into a separate branch of Engineering during the early 19th century. Industrial revolution that took place in Europe played a key role in the emergence of this branch as an independent discipline.

Do you want to know what Mechanical Engineering is all about? Want a proper definition? Next paragraph will be of help to you then!


Mechanical Engineering is the branch of Engineering that deals with design, manufacturing and operation of machinery. This branch uses concepts of engineering, physics and material science for design, manufacturing, operation and maintenance of mechanical systems.


Some of the important topics covered in this branch of engineering include- material science, engineering physics, theory of machines, kinematics of machines, thermodynamics, manufacturing etc. With development in technology, new topics have also been introduced, like- CADD (Computer Aided Design and Drawing), nanotechnology, mechatronics etc.


Concepts of mechanical engineering extend along to other engineering branches also. Some such branches are- industrial engineering, automobile engineering, power engineering, production engineering, electrical engineering, civil engineering, metallurgical engineering and aeronautical engineering.


This engineering branch touches our day to day lives directly or indirectly. From household equipment like washing machines and grinders to buses and trains that we use for transportation, mechanical engineering and machines are involved in one way or the other!


The above paragraph shows how important this branch of engineering really is! Let us check out important course details in the next section.


Diploma in Mechanical Engineering: Course details

Diploma in Mechanical Engineering is a 3 years long program. The academic program is divided into 6 semesters, with each semester lasting for a period of 6 months.


Few institutes are also offering Integrated program- Diploma + B.Tech. Degree in Mechanical Engineering.


Diploma in Mechanical Engineering course trains students in areas such as- machine design, material science, thermodynamics, kinematics, engineering drawing, physics etc.


Eligibility criteria

Students who have passed 10th standard are eligible to pursue this course. This course can also be pursued after 10+2 Science stream too (Mathematics group)!


Diploma in Mechanical Engineering Admission and Colleges

Many polytechnic, technical education and engineering institutes across India are offering this program. Most institutes usually have the ‘direct admission’ process. Interested students have to approach the institute and fill up the admission form. Seats will be allotted to deserving students on the basis of marks scored by them in 10th board examination (usually in Mathematics and Science subjects).


Diploma in Mechanical Engineering Syllabus

To get a better idea about the course structure, let us go through some of the important subjects present in Diploma in Mechanical Engineering program. Note: Not all the subjects present in this course have been mentioned. Only the important ones have been listed.

Note: This is the syllabus of GTU (Gujarat Technological University). Syllabus and course structure may vary from one University/State to another. However, the core subjects and syllabus will remain the same. Most of the subjects mentioned above have both classroom lectures and practical sessions associated with them. In case of last year (5th and 6th semesters), project work is present. Students will have to undertake and complete a project work related to the field of Mechanical Engineering, under the guidance of faculty members.


Elective subjects may vary from one institute/university to another. Usually, elective subjects are related to topics like-Manufacturing Systems, Power Plant Engineering, Thermal Systems, Hydraulic Systems, Pneumatic Systems and Operations Management.


Higher studies and PG courses

After completing Diploma in Mechanical Engineering program, one may go for Bachelor’s Degree (B.E./B.Tech.) in Mechanical Engineering! In most Degree Engineering colleges, certain percentages of seats are reserved for Diploma certificate holders. This entry is known as the lateral entry. Diploma holders with good grade may make use of lateral entry and join B.E./B.Tech. Mechanical Engineering program’s 2nd academic year (directly). This way, Diploma holders may make use of the ‘DtoD’ switch and earn a Bachelor of Engineering/Technology Degree!

After that, one may go for Master’s education or PG Diploma programs. M.E./M.Tech. programs and PG Diploma courses will enable one to specialize in disciplines within the field of Mechanical Engineering. Some such areas of specialization are-

  • Automobile Engineering
  • Power Engineering
  • Production Engineering
  • Industrial Engineering
  • Aeronautical Engineering
  • Marine Engineering
  • Robotics
  • Biomechanics
  • Piping Engineering
  • CADD
  • Mechatronics
  • Fluid Mechanics
  • Thermodynamics


Other than traditional PG courses like Master’s courses and PG Diploma courses, one may also go for PG certificate and skill enhancing training courses after graduation. If you are interested in management program, you may go for MBA program (after graduation)!


Diploma in Mechanical Engineering scope & jobs

Mechanical Engineering is one of the core branches of engineering. When it comes to job opportunities and career prospects, it is an evergreen branch!


Mechanical Engineering deals with design, production, installation, operation and maintenance of machine systems. Industries and units that need machine systems for functioning thus need mechanical engineers to take care of the above mentioned tasks. Especially sectors related to manufacturing, automobile, aerospace and energy are well known to recruit mechanical engineers.


Since concepts of mechanical engineering extend along to other branches of engineering (such as electrical, civil and metallurgy engineering), mechanical engineers will be able to find a job in areas related to those fields also, like- construction sector, power transmission and production etc.


In short, diverse job opportunities are available in front of Diploma holders. Government and private sector offers many job opportunities to mechanical engineers.


Talking about Government sector, well known recruiters include- BHEL, ONGC, PWD, Indian Railways, Indian Armed Forces, SAIL, Municipal Corporations, State Road Transportation Boards, Metro Rail Corporations, HSCL, RINL, HAL, GAIL, Coal India Limited etc.


When it comes to Private sector, some of the well known recruiters include- Automobile Companies (TATA, Maruti Suzuki, Mahindra & Mahindra etc), L&T, JBM Auto, TATA Steel, Reliance group, Kirloskar etc.


Job profiles available (depending on specialization) include-

  • Mechanical Engineer
  • Production Engineer
  • Maintenance Engineer
  • Automobile Engineer
  • Process Control Engineer
  • Quality Control Engineer
  • CADD Specialist
  • Piping Engineer
  • Aeronautical Engineer
  • Contractor


Starting salary depends on a number of different factors. Prominent factors are- profile of the employer, employee skills, aptitude and grades attained by the employee. General starting salary is around 20-30k Rupees per month. In case of Government job, salary will be based on Pay Band and scale.
