Mechanical engineering: Introduction, Course, Scope and Career
What is mechanical engineering
Mechanical engineering is the study of
· Application of principles of
engineering, physics and material science
· Application of science to produce
machines from small pin to jet engines
· Translation of theoretical research
into practical situation
· How energy and mass transfer takes
place in industrial and domestic operations
· Mechanism behind working of machines
· Design of machines
· Selection of metals and materials
· Study of fluid flow and its mechanics
study of energy, mass, machines, materials, design, thermal and kinetics
· Application of mathematics in
engineering
What will you study in mechanical engineering
You will be studying following major subjects under mechanical
engineering
· Fluid mechanics: It deals with the
mechanism and characteristics of different types of mechanisms, effect of
various factors and parameters on the fluid flow conditions and fluid flow
properties. Types of pumps and its characteristics etc
· Material science : it deals with the
properties, characteristics and selection criteria of different type of
materials
· Heat and mass transfer: Modes of heat
transfer, different types of heat exchangers and their designs, heat transfer
under steady state and unsteady state conditions, mass transfer laws, mass
transfer equipments and their working and design etc
· Thermodynamics: It deals with the topic for the condition of
effect off and on thermal energy under dynamic conditions and Thermodynamics
laws covered under physics subject during class 12th will fulfil the
prerequisites for this course
· Machine design: It covers the various
aspects of machine design and the parameters and factors affecting the best
design
· Computer aided design: Student will
design the equipment and machine or the part of it and will do the drawing and
design of the same using software on computer
Why mechanical engineering
· Mechanical engineering is one of the
largest broadcast and evergreen branches of core engineering since long.
· It is the heart of all industry where
machines are used.
· Machines and Automations in machines have
changed all the concept of life and made life more easy cant flexible.
· Due to Rapid growth of machinery automation
design energy and innovation sector.
· Mechanical Engineering has become one of
the fastest growing segment and sector of world's economy.
· Mechanical sector becomes the parameter of
GDP rate.
· Though Number of innovations has taken
place in mechanical engineering sectors the process of innovation and research
is continuous and makes the mechanical engineering.
Who should select mechanical engineering as a career?
· Those who have aptitude for/Desire
learning.
· Mathematics and designing skills.
· Complex problem solving.
· Sciences and its correlations with machine operations
and design.
· Mechanism of operations.
· Development and design of new machines.
· To work with cutting edge Technology.
· Ways to improve the efficiency and
effectiveness of Machines and equipments.
· Time management and flexibility in terms of
time and location.
· Inquisitive skills.
· Creativity and thinking skill.
· Teamwork attitude and mindset for hard work
.
· Girls can also select it as a career option
as they are having an opportunity to work on the project, design and
consultancy divisions.
Does mechanical engineering have any scope after four
years?
Yes, it has a scope of
employment, entrepreneurship and further study.
· Government is focusing on Entrepreneurship
and more number of companies are coming up in mechanical sector.
· It is a Core and production oriented
branch, hence very few external factors can affect its growth.
· Irrespective of core Mechanical Engineering
Company, all the industries ( it may be SME's, SSI, LSI or MSI) requires
mechanical engineer.
· Students have huge scope in public sector
units, if they clear GATE examination, they may get direct interview call and
placement in public sectors like ONGC.
· Strong job opportunities are available in
the sector like design and development, oil and gas industry, engineering
consultancy, food and beverages industry, textile engineering industry, Steel
industry, etc.
· Giant companies hiring mechanical engineers
are BARC, SIMENS, HERO, HONDA, SKF, Kylem, Tisco, Cummins, ISRO, SAIL, MARUTI
SUZUKI, CEAT , NTPC, ONG ABB, ARAI, BHEL, Ambuja Cement, SUZLON, ITT, MRF
Tyres, ALSTOM, RIL, ESSA STEEL, TAFE, GODREJ, JSW STEEL, GE ENERGY, MAHINDRA ,
HAL , THERMAX etc.
Threats
In addition to the
above strengths and scope for mechanical engineering few threats are also there
which one should consider while selecting mechanical engineering, as a study
option.
· Number of seats for mechanical engineering
in the state increased vertically, above 16000 seats, which increase the
employment competition among the students.
· Lack of state of art facilities for
mechanical engineering in many institutes spoil the four years of Engineering
and do not provide good placement opportunities and assistance for better
growth, students should be ready to work at remote places and relocation.
Difference between mechanical engineering, Automobile
engineering and Mechatronics engineering
· About 60% subjects to be studied in
automobile engineering and Mechanical engineering are common.
· Engineering is a specialised branch,
whereas mechanical engineering is a General branch.
· Mechatronics engineering is a blend of
mechanical engineering and electronics engineering.
· Communication engineering is not a part of
mechatronics engineering.
· About 60% to 70% syllabus of mechatronics
engineering is from electronics engineering and rest is from mechanical engineering.
· Students having mechatronics engineering
have limited scope for government job, due to issues of equivalency of
mechatronics engineering and mechanical engineering.
