MEMechanical Engineering is the oldest as well as the widest branch of all the engineering departments. It spans from the age of Archimedes when the massive power of lever arm was first introduced, and still evolving through technological searches with innovations like spacecraft for terrestrial exploration. Beginning with the classical mechanics, the mechanical engineering has eventually expanded its realm with the implementation of thermodynamics, fluid mechanics, heat transfer and material science.  Mechanical engineering is an accomplished engineering field by virtue of its capability to extract energy from the hydrocarbon fuels to convert into work which is later enacted on static systems to become dynamic. While transferring from stationary to moving, all the mechanisms required for it also are being designed, manufactured and installed by the mechanical personnel. Mechanical engineers are constantly enlarging the perimeters of today’s utility world by inventing more efficient machines to produce safer, cheaper and reliable products. Thus, the applicability of mechanical engineering remains dominant equally in both the household and industrial yards.

The Bachelor degree program offered by the Department of Mechanical Engineering is intended to prepare students for successful careers in their job fields coping with the needs of modern days. The course of study is designed to enrich the students with theoretical as well as experimental knowledge essential to enter the fields of design, production, sales and management. At the same time it builds the foundation footing in the fresh graduates for further higher studies.

Mechanical engineers are in demand in many types of manufacturing plants as well as in research, academic and governmental organizations. Specific positions involve research and development, design of equipment or systems, supervision of production, plant engineering, administration, sales engineering, testing and evaluation of machines and entire plants and teaching. The BSME program also prepares them to address current and future problems in areas such as energy storage (fossil or renewable), alternative fuels, hazardous (nuclear) waste management, environmental control, more efficient energy conversion methods and biomedical engineering. The undergraduate degree program is structured encompassing three primary academic areas viz. thermal-fluid science engineering, systems and design engineering and materials science engineering.

Besides, the degree program, the Department of Mechanical Engineering teach fundamental core courses in engineering which supports the degree programs in other departments of the College of Engineering and Technology. The Department also undertakes research, training, consultancy and publication to a limited extent. Some of this work is being carried out under the umbrella of Centre for Technological Research Training and Consultancy (CTRTC).

OBJECTIVES

Mechanical engineering is concerned with motion and the processes whereby other energy forms are converted into motion. Modern technological society has its roots in mechanical engineering. Mechanical engineers made significant contribution to modern civilization. Such contributions took the form of making engines to power ships, trains, motorcars, spacecraft; designing power plants for converting the energy in fuels, atoms, waterfalls and sunlight into useful mechanical forms; and constructing intelligent machines and robots. Thus the mechanical engineers provided modern society with devices and systems to utilize the energy form that causes motion. As a branch of engineering education, mechanical engineering is concerned with all forms of energy conversion and transmission, the flow of fluids and heat, the development, design and operation of machinery and equipment and transportation processes. The mechanical engineering program is designed to give the student fundamental preparation to enter into wide variety of careers involving research, design, operation, production or management of production facilities.
