As an example, automotive engines convert chemical energy enthalpy from the fuel into heat, and then into mechanical work that eventually turns the wheels.
Mechanics of materialsthe study of how different materials deform under various types of stress Fluid mechanicsthe study of how fluids react to forces  Kinematicsthe study of the motion of bodies objects and systems groups of objectswhile ignoring the forces that cause the motion.
Thermodynamics Practical detail b tech mechanical heat are used by mechanical engineers in the fields of heat transferthermofluidsand energy conversion.
Areas of research[ edit ] Mechanical engineers are constantly pushing the boundaries of what is physically possible in order to produce safer, cheaper, and more efficient machines and mechanical systems. Current uses of this technology to date include welding the seams of the aluminum main Space Shuttle external tank, Orion Crew Vehicle test article, Boeing Delta II and Delta IV Expendable Launch Vehicles and the SpaceX Falcon 1 rocket, armor plating for amphibious assault ships, and welding the wings and fuselage panels of the new Eclipse aircraft from Eclipse Aviation among an increasingly growing pool of uses.
Subdisciplines of mechanics include Staticsthe study of non-moving bodies under known loads, how forces affect static bodies Dynamics the study of how forces affect moving bodies. Outside the factory, robots have been employed in bomb disposal, space explorationand many other fields.
Examples of MEMS components are the accelerometers that are used as car airbag sensors, modern cell phones, gyroscopes for precise positioning and microfluidic devices used in biomedical applications. 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.
Fatigue failure occurs because of imperfections in the object: Micro electro-mechanical systems MEMS [ edit ] Micron-scale mechanical components such as springs, gears, fluidic and heat transfer devices are fabricated from a variety of substrate materials such as silicon, glass and polymers like SU8.
In this way, machines can be automated through the use of electric motorsservo-mechanismsand other electrical systems in conjunction with special software. Continuum mechanicsa method of applying mechanics that assumes that objects are continuous rather than discrete Mechanical engineers typically use mechanics in the design or analysis phases of engineering.
However, with the advent of computer numerically controlled CNC manufacturing, parts can now be fabricated without the need for constant technician input. Some technologies at the cutting edge of mechanical engineering are listed below see also exploratory engineering. Optionally, an engineer may also manually manufacture a part using the technical drawings.
They allow businesses to save money on labor, perform tasks that are either too dangerous or too precise for humans to perform them economically, and to ensure better quality. Manually manufactured parts generally consist spray coatingssurface finishes, and other processes that cannot economically or practically be done by a machine.
Fluid mechanics might be used to design a ventilation system for the vehicle see HVACor to design the intake system for the engine. Structural analysis is often used by mechanical engineers after a failure has occurred, or when designing to prevent failure.
If the engineering project were the design of a vehicle, statics might be employed to design the frame of the vehicle, in order to evaluate where the stresses will be most intense. Thermodynamics Thermodynamics is an applied science used in several branches of engineering, including mechanical and chemical engineering.
Technical drawing and CNC Drafting or technical drawing is the means by which mechanical engineers design products and create instructions for manufacturing parts. Thermodynamics and thermo-science[ edit ] Main article: Drafting is used in nearly every subdiscipline of mechanical engineering, and by many other branches of engineering and architecture.
Mechatronics and Robotics Mechatronics is a combination of mechanics and electronics. Kinematics is often used in the design and analysis of mechanisms.
Once theory is applied to a mechanical design, physical testing is often performed to verify calculated results.
At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Robots are used extensively in industrial engineering. If these systems do not break, failure analysis might be employed to determine the cause.
It 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.
Structural analysis may be used in an office when designing parts, in the field to analyze failed parts, or in laboratories where parts might undergo controlled failure tests. These robots may be of any shape and size, but all are preprogrammed and interact physically with the world. Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions.
Integrated software controls the process and communicates the contents of the CD to the computer. The innovative steady state non-fusion welding technique joins materials previously un-weldable, including several aluminum alloys. Robots are also sold for various residential applications, from recreation to domestic applications.Proposed Syllabus For mint-body.com Program in Mechanical Engineering By TCA-SP Workshop Practice 0 0 3 3 II SEMESTER HSS-S Communicative English 3 1 0 4 ISC-ST Programming and Computing 3 0 0 3 PRT-S mint-body.com Project-I 0 0 6 4 SST-S Summer Trainning 0 0 2 2 VIII SEMESTER MEE-ST Measurements and.
