A description of engineering mechanics

What is Mechanical Engineering?

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.

Technical drawing and CNC Drafting or technical drawing is the means by which mechanical engineers design products and create instructions for manufacturing parts. However, it is sufficient to know the normal and shear components of strain on a set of three mutually perpendicular directions.

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.

Many schools will require an internship or a co-op program so that you are able to get hands-on experience in this field. Sample Problems have been integrated throughout, including problems with computer-oriented solutions.

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.

Engineering Mechanics: Dynamics

A major in Engineering Mechanics will prepare you for a career where you can design, analyze and build structures and machines.

Engineering strain[ edit ] The Cauchy strain or engineering strain is expressed as the ratio of total deformation to the initial dimension of the material body in which the forces are being applied.

The normal strain is positive if the material fibers are stretched and negative if they are compressed. Key Concepts are highlighted within the theory presentations and chapter reviews offer itemized summaries of the material covered.

Some systems, such as the perforated top sections of some plastic bags, are designed to break. In order to accomplish this, a broad range of skills are needed.

Making things work better, more efficiently, quickly and less expensively will be part of your job. Strains measure how much a given deformation differs locally from a rigid-body deformation. Soil and rock mechanics[ edit ] Main articles: Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions.

Deformation (mechanics)

These appear in the problem sets following the Sample Problems. Statics teaches students the appropriate techniques and then applies them consistently in solutions of mechanics problems. Outside the factory, robots have been employed in bomb disposal, space explorationand many other fields.

An engineering geology report describes the objectives, methodology, references cited, tests performed, findings and recommendations for development and detailed design of engineering works. You will know the effects of forces and torques on particles and rigid bodies and use these concepts to analyze safety, stability, and design.

To create a robot, an engineer typically employs kinematics to determine the robot's range of motion and mechanics to determine the stresses within the robot. Structural analysis and Failure analysis Structural analysis 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.

If there is an increase in length of the material line, the normal strain is called tensile strain, otherwise, if there is reduction or compression in the length of the material line, it is called compressive strain. Engineering Mechanics questions and answers with explanation for interview, competitive examination and entrance test.

Fully solved examples with detailed answer description, explanation are given and it would be easy to understand. Engineering mechanics is the engineering science that deals with the effects of forces and torques on particles, rigid bodies, or deformable media.

Engineering Mechanics Questions and Answers

Mechanics is typically subdivided into statics, dynamics, and mechanics of deformable bodies. Fluid Mechanics 1 Dr. C.

Check back frequently as new jobs are posted every day. Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body.

A deformation may be caused by external loads, body forces (such as gravity or electromagnetic forces), or changes in temperature, moisture content, or chemical reactions, etc.
