Make a mark with mechanical engineering

Mechanical Engineering is the discipline that applies engineering, physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product life cycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. It is the branch of engineering that involves the design, production, and operation of machinery.

The department of Mechanical Engineering at Crescent Institute was started in 1984 and is one of the oldest departments. Twenty seven batches of U.G. students have passed out, with many university ranks and gold medals. The programmes of the Department have been accredited by the National Board of Accreditation (NBA).

A high degree of professionalism is inducted to the students through the student’s chapters of professional associations such as American Society of Mechanical Engineers (ASME), Society of Automotive Engineers (SAE), Indian Society for Heating Refrigeration and Air-conditioning (ISHRAE) and Society of Mechanical Engineers (SME). These bodies organize seminars for students on topics of current importance and global relevance to industry.

The department organizes programmes to provide the students with industrial and practical experience through training and project work in industries to meet the industrial requirements and face real life situations effectively and boldly.

Modern multimedia teaching technologies are used to supplement lectures and enhance the quality of teaching. Computer aided learning packages on different subjects are available for self-learning. Industrial visits are arranged for students to gain practical exposure. In addition, guest lectures and panel discussions are arranged by inviting eminent persons from reputed organizations.

Almost all the eligible students of final year mechanical engineering get placements during the campus recruitment. Some of the major recruiters include Mahindra and Mahindra Ltd, Caterpillar, Larsen & Toubro, West Asia Ltd, Wipro, Infosys, Cognizant Technology Solutions, Hewlett-Packard and Tata Consultancy Services.

Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology.

It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modeling of biological systems.

Coursework

Standards set by each country's accreditation society are intended to provide uniformity in fundamental subject material, promote competence among graduating engineers, and to maintain confidence in the engineering profession as a whole.

The specific courses required to graduate, however, may differ from program to program. Universities and Institutes of technology will often combine multiple subjects into a single class or split a subject into multiple classes, depending on the faculty available and the university's major area(s) of research.
The fundamental subjects of mechanical engineering usually include:

Mathematics (in particular, calculus, differential equations, and linear algebra)

Basic physical sciences (including physics and chemistry)

Statics and dynamics

Strength of materials and solid mechanics

Materials Engineering, Composites

Thermodynamics, heat transfer, energy conversion, and HVAC

Fuels, combustion, Internal combustion engine

Fluid mechanics (including fluid statics and fluid dynamics)

Mechanism and Machine design (including kinematics and dynamics)

Instrumentation and measurement

Manufacturing engineering, technology, or processes

Vibration, control theory and control engineering

Hydraulics, and pneumatics

Mechatronics, and robotics

Engineering design and product design


Drafting, computer-aided design (CAD) and computer-aided manufacturing (CAM)

Mechanical engineers are also expected to understand and be able to apply basic concepts from chemistry, physics, chemical engineering, civil engineering, and electrical engineering. All mechanical engineering programs include multiple semesters of mathematical classes including calculus, and advanced mathematical concepts including differential equations, partial differential equations, linear algebra, abstract algebra, and differential geometry, among others.


In addition to the core mechanical engineering curriculum, many mechanical engineering programs offer more specialized programs and classes, such as control systems, robotics, transport and logistics, cryogenics, fuel technology, automotive engineering, biomechanics, vibration, optics and others, if a separate department does not exist for these subjects.


Mechanical engineers typically do the following:

Analyze problems to see how mechanical and thermal devices might help solve the problem.

Design or redesign mechanical and thermal devices using analysis and computer-aided design.

Develop and test prototypes of devices they design.

Analyze the test results and change the design as needed.

Oversee the manufacturing process for the device.

Mechanical engineers design and oversee the manufacturing of many products ranging from medical devices to new batteries. They also design power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines as well as power-using machines, such as refrigeration and air-conditioning systems.
