Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






2. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






3. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






4. The use of simple machines to multiply the output force of a mechanical system.






5. The act of breaking a particular subject into different parts to achieve clarity of understanding.






6. The use of 3D CAD drawings to create real models of a product within a sort of time.






7. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






8. The judgement of the end result based upon given criteria.






9. The field of knowledge relating to materials as they exists on a molecular or atomic level.






10. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






11. Someone who starts a business.






12. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






13. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






14. The capacity to do work or exert effort.






15. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






16. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






17. Stored energy or energy at rest.






18. The superimposition of sine waves on electromagnetic carrier waves.






19. Restriction or limit placed on a product.






20. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






21. The process of turning abstractions of thought into concrete ideas.






22. Trade of products and services on a global scale.






23. A production process in which the part or product moves down a line from one station to the next while parts are added.






24. The capacity to do work or exert effort.






25. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






26. Creating things through the process of planning.






27. A device that orbits the Earth and receives messages from one location and transmits them to another.






28. A production system in which products are made one at a time according to customer's specifications.






29. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






30. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






31. Studying the effects of a given technology to determine its impact.






32. A method of obtaining energy from waste products






33. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






34. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






35. The act of putting different things together to form a new product or idea.






36. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






37. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






38. A group of people working together to accomplish a common goal.






39. The basic framework of a system






40. The use of computers in each stage of the design process.






41. The splitting of the nucleus of an atom.






42. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






43. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






44. Current flow in which electrons reverse direction at regular intervals.






45. The path by which a message travels from the sender to receiver.






46. A language - used to write computer programs - that can easily be translated into machine language.






47. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


48. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






49. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






50. The path by which electric current or pulses flow.
