Topics for mechanical engineering

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.

Describe the entire process, and what things an engineer needs to watch out for. Optionally, an engineer may also manually manufacture a part using the technical drawings. Engineers often use online documents and books such as those published by Topics for mechanical engineering [29] to aid them in determining the type of failure and possible causes.

Mechanical engineering

Some systems, such as the perforated top sections of some plastic bags, are designed to break. Structural analysis is often used by mechanical engineers after a failure has occurred, or when designing to prevent failure. However, with the advent of computer numerically controlled CNC manufacturing, parts can now be fabricated without the need for constant technician input.

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.

Drafting is used in nearly every subdiscipline of mechanical engineering, and by many other branches of engineering and architecture. The innovative steady state non-fusion welding technique joins materials previously un-weldable, including several aluminum alloys.

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. Thermodynamics and thermo-science[ edit ] Main article: If these systems do not break, failure analysis might be employed to determine the cause.

Technical drawing and CNC Drafting or technical drawing is the means by which mechanical engineers design products and create instructions for manufacturing parts. Micro electro-mechanical systems MEMS [ edit ] Micron-scale mechanical components such as springs, gears, fluidic and heat transfer devices are fabricated Topics for mechanical engineering a variety of substrate materials such as silicon, glass and polymers like SU8.

What system could be implemented to reduce transportation costs? Static structural failure occurs when, upon being loaded having a force applied the object being analyzed either breaks or is deformed plasticallydepending on the criterion for failure.

Many companies employ assembly lines of robots, especially in Automotive Industries and some factories are so robotized that they can run by themselves. Mechanical engineers use thermo-science to design engines and power plantsheating, ventilation, and air-conditioning HVAC systems, heat exchangersheat sinksradiatorsrefrigerationinsulationand others.

There are many important elements that can destroy an entire project. 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.

In this way, machines can be automated through the use of electric motorsservo-mechanismsand other electrical systems in conjunction with special software. As an example, automotive engines convert chemical energy enthalpy from the fuel into heat, and then into mechanical work that eventually turns the wheels.

Do you consider this an evolution, or a danger for the human race? Dynamics includes kinematics about movement, velocity, and acceleration and kinetics about forces and resulting accelerations. What measures can people apply to reduce the pollution caused by their cars?

Integrated software controls the process and communicates the contents of the CD to the computer. Mechanics of materialsthe study of how different materials deform under various types of stress Fluid mechanicsthe study of how fluids react to forces [27] Kinematicsthe study of the motion of bodies objects and systems groups of objectswhile ignoring the forces that cause the motion.

For sure this is a solution to reduce the costs, but it would be a disaster for many poor countries. 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. 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.

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.

Mechanics Mechanics is, in the most general sense, the study of forces and their effect upon matter.

Once theory is applied to a mechanical design, physical testing is often performed to verify calculated results. You need to apply principles from different areas of study and combine them to create a device that actually works. Kinematics is often used in the design and analysis of mechanisms.

It plays an important role in the future construction of airplanes, potentially replacing rivets. Manually manufactured parts generally consist spray coatingssurface finishes, and other processes that cannot economically or practically be done by a machine.

Is the environment damaged? What are the details that could be adjusted? Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions. 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.seminar topics for mechanical engineering.
