Adaptive to change  Definition of Engineering According to ABET, Engineering is: “The profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to utilize, economically, the material forces of nature for the benefit of mankind. According to Webster’s Dictionary: Engineering is “The application of math and science by which the properties of matter and the sources of energy in nature are made useful to people.”  Engineering and Science “Both the engineer and scientist are thoroughly educated in the mathematical and natural sciences, but the scientist primarily uses this knowledge to acquire new knowledge, whereas the engineer applies this knowledge to design and develop usable devices, structures and processes. In order words. The scientist seeks to know, the engineer aims to do”. -Eddie, Jenison, Mashaw and Northup, Engineering Fundamentals and Problem Solving. Engineers, who are they? An engineer is Engineers apply math, science, and judgment a professional for the betterment of society through: practitioner of engineering, who applies knowledge in Research & Development Design Manufacturing & Operation Construction natural or physical sciences, mathematics, and ingenuity to Sales Management Consultancy develop solutions Teaching of technical problems. Above all, engineers are problem solvers who make things work better, more efficiently, faster and cheaper. 1.1 Engineering as a profession What is Engineering?

Research – discover new or improved application of the principles in new contexts, new data, new methods 2. Development – apply the discovered principles to develop model or prototype 3. Design – come up with working models or real solution that fulfill the intended functions 4. Testing – provide services for testing and inspection to ensure desired quality of product or services; simulate instances and environments for safety and reliability 1.3 Engineering function (cont.) 5. Construction, Manufacturing & Production – prepare sites & facilities like plant layout, equipment, processes and tools; integrate the flow of materials, components, and personnel 6. Operation & Maintenance – Responsible for setting up and maintaining the production line; control machines, plants, and organizations; communicate and supervise personnel for reliable and economical operation of equipment 7. Sales – since products become more and more technically complex, the need for sales engineers with technical background who are able to communicate effectively with customers are growing 1.3 Engineering function (cont.) 8. Management – manage engineering companies; work between sales, customers and production sites; must have good interpersonal skills 9. Consultancy – provide engineering expertise in design, installation, and upkeep of a product or service. 10. Teaching – last but not least, engineers share knowledge in society, university, training centers, etc. Engineering Functions 1 2 1. RESEARCH 2. DEVELOPMENT 3. DESIGN 4. TESTING 5.

The mechanical engineer may design a component, a machine, a system or a process. They will analyze their design using, for examples, the principles of motion, energy, and force or other related principles to insure the product functions safely, efficiently, reliably, and can be manufactured at a competitive cost. Mechanical engineers work in the automotive, aerospace, chemical, computer, communication, paper, and power generation industries. Mechanical engineers will be found in virtually any manufacturing industry. Increasingly, mechanical engineers are needed in the environmental and bio-medical fields. Indeed virtually every product or service in modern life has probably been touched in some way by a mechanical engineer. What is Mechanical Engineering? Mechanical engineering is the second largest and one of the oldest disciplines; broadest of all engineering disciplines. Mechanical engineers apply the principles of mechanics and energy to the design of machines and devices: ENERGY and MOTION What will you study as an ME student? Forces, motion, structures: statics, dynamics, kinematics, mechanics of solids and fluids. Energy: thermodynamics, heat transfer Materials: materials engineering & processing, manufacturing.
