‘Mechanical engineers are also material scientists’

Mechanical engineering is one of the oldest engineering branches which has become more interdisciplinary in nature, writes Neelanchali Asija Bhalla

Mechanical Engineering is one of the oldest branches of engineering. This may explain why it is also referred to as the ‘mother’ of all the other engineering branches. Another significant feature is its vast and diverse application. There are tremendous growth opportunities for mechanical engineers in manufacturing industries, aerospace and automotive industries, government organisations such as NTPC, BHEL, ONGC, HAL, PWDs etc, and defence organisations such as DRDO, DMSRDE, DMRL etc. The ‘Make in India’ campaign has further boosted the manufacturing sector, and widened the job prospects. Mechanical engineering in today’s world has evolved to a great extent. Earlier, the understanding of mechanical engineers was limited to mechanics, thermodynamics, kinematics, engineering drawing etc, but now, the mechanical engineering branch has become more interdisciplinary in nature. 

Mechanical engineers are focussing on new research areas like nanotechnology, design and development of composite materials for aerospace and defence applications. They are also engaged in biomedical applications covering the design and development of implants for physically challenged people, environment conservation by promoting green technology like additive manufacturing and sustainability. Mechatronics and automation is yet another highly evolved branch drawn from mechanical engineering, which includes an exhaustive combination of various engineering disciplines like mechanical, electrical, electronics and communications and Computer Science. 

Mechanical engineers work with a wide variety of materials including metals, ceramics, composites and polymers. So essentially, all mechanical engineers are also material scientists. This materials knowledge allows the mechanical engineer to predict the performance and reliability of materials under various environmental conditions. 

The BTech programme in Mechanical Engineering offered by Bennett University covers major aspects and emerging areas of the mechanical engineering domain. The programme allows students to study electives from areas such as automotive engineering design, aerospace engineering, industrial and production engineering, biomechanics and bioengineering and energy systems. It prepares the students for roles across industries and for areas related to noise and vibration in industrial outfits, fluid flow patterns and industrial pipelines, computer controlled robotic and mechatronics systems, among others. The department encourages the students to solve real-life problems and be innovative.
