Mechanical Engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. This engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering, and product lifecycle 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. 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. Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics.
The Department of Mechanical Engineering at Akido College of Engineering is to provide students with a sound mechanical engineering education, enhance the understanding and application of mechanical engineering principles, for techno economical development of the country, and improve the quality of life of our citizens through teaching, research, and outreach programs. The mission is further to provide an environment where students have extensive avenues to excel, improve technical exposure and develop personality and then get placed in PSUs, MNCs and reputed companies with good future so that students have global presence, in various roles and responsibilities. . With excellent teaching and learning environment it provides a platform to instill high motivation, moral values and leadership in its students. The Department offers eight-semester Bachelor of Technology (B.Tech.) course with an annual intake of sixty.
The field of mechanical engineering can be thought of as a collection of many mechanical engineering science disciplines. Several of the subjects which are typically taught at the undergraduate level are listed below, with a brief explanation and the most common application of each. Some of these subjects are unique to mechanical engineering, while others are a combination of mechanical engineering and one or more other disciplines. Most work that a mechanical engineer does uses skills and techniques from several of these subjects.
Mechanics is, in the most general sense, the study of forces and their effect upon matter. Typically, engineering mechanics is used to analyze and predict the acceleration and deformation (both elastic and plastic) of objects under known forces (also called loads) or stresses. The topics of mechanics include statics, dynamics (kinetics), kinematics, and continuum mechanics.
Thermodynamics is an applied science used in several branches of engineering, including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermo fluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Drafting or technical drawing is the means by which mechanical engineers design products and create instructions for manufacturing parts. A technical drawing can be a computer model or hand-drawn schematic showing all the dimensions necessary to manufacture a part, as well as assembly notes, a list of required materials, and other pertinent information. A U.S. mechanical engineer or skilled worker who creates technical drawings may be referred to as a drafter or draftsman. Drafting has historically been a two-dimensional process, but computer-aided design (CAD) programs now allow the designer to create in three dimensions.
A materials mechanical engineer focuses on properties of materials and their effect on design, fabrication, quality, and performance. They work to create materials which can be cast, forged, stamped, rolled, machined or welded.
Strength of Material is the branch of mechanical engineering (and also civil engineering) devoted to examining why and how objects fail and to fix the objects and their performance. Structural failures occur in two general modes: static failure, and fatigue failure. Static failure occurs when; upon being loaded (having a force applied) the object being analyzed either breaks or is deformed plastically, depending on the criterion for failure. Fatigue failure occurs when an object fails after a number of repeated loading and unloading cycles. Fatigue failure occurs because of imperfections in the object: a microscopic crack on the surface of the object, for instance, will grow slightly with each cycle (propagation) until the crack is large enough to cause ultimate failure.
Fluid Mechanics deals with the properties of fluid and its effect on surrounding under static and dynamic condition. In Static fluid mechanics we study the properties of fluid when it is at rest and in fluid dynamic, properties of fluid are to be studied when fluid flow take place. Hydraulic machines such as hydraulic turbine and hydraulic
Manufacturing Technology is a wide area of Mechanical Engineeringin which students get the knowledge of manufacturing a great variety of machines, robotics and other equipment. The manufacturing engineer may be responsible for the design, selection of materials, specifications and the improvement of production processes and equipment. Responsibility for plant layout, production management and control, as well as plant maintenance is also required of manufacturing engineers.
IC Engine is the discipline of Mechanical Engineering in which, the students gets knowledge of different types of engine which are used in transport vehicle. The subject has it’s a wide application in automobile engineering field. Also with the knowledge of Gas Turbine students has an opportunity in Power Plant area
Mechatronics is an interdisciplinary branch of mechanical engineering, electrical engineering and software engineering that is concerned with integrating electrical and mechanical engineering to create hybrid systems. In this way, machines can be automated through the use of electric motors, servo-mechanisms, and other electrical systems in conjunction with special software. A common example of a mechatronics system is a CD-ROM drive. Mechanical systems open and close the drive, spin the CD and move the laser, while an optical system reads the data on the CD and converts it to bits. Integrated software controls the process and communicates the contents of the CD to the computer. Robotics is the application of mechatronics to create robots, which are often used in industry to perform tasks that are dangerous, unpleasant, or repetitive.
This field is not new, as the basis of Finite Element Analysis (FEA) or Finite Element Method (FEM) dates back to 1941. But evolution of computers has made FEA/FEM a viable option for analysis of structural problems. Many commercial codes such as ANSYS, Nastran and ABAQUS are widely used in industry for research and design of components.
The breadth of the mechanical engineering discipline allows students a variety of career options. Mechanical Engineering graduates can look for employment in almost every type of industry. The traditional mechanical industries include transportation vehicles, power plants, automotive, steel and metal, farm implements, heavy equipment and machine tools. Mechanical engineering involves the design, development and construction of nearly all of the physical devices and systems which technology has produced. Typical examples include automobiles, aircrafts, turbines, robotics, agriculture machinery, etc. Mechanical engineers are also concerned with the operations of all kinds of machinery, and the production of power. They much conceive research, design, develop, manufacture, test and sell equipment for these purposes.
