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. A resource that is entered into a system.






2. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






3. A circuit in which electricity flows along a single path to more than one device.






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






5. The capacity to do work or exert effort.






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






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






8. 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.






9. The unlawful acquisition of some one's personal information for use without their consent.






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






11. The use of pressurized liquid or gasses to control and transmit power.






12. The use of force to act on an object in order to move move the object in the same direction as the force.






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






14. A group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






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






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






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






18. 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.






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






20. 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.






21. Energy in motion.






22. The splitting of the nucleus of an atom.






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






24. The formal rules that guide the design process.






25. A method of obtaining energy from waste products






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






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






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






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






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


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






32. 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.






33. The technology field focused on sending messages and other in formation using different means.






34. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






35. The basic framework of a system






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






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






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






40. Restriction or limit placed on a product.






41. 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.






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






43. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






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






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






46. 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.






47. The capacity to do work or exert effort.






48. The money a business makes after all expenses have been paid






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






50. Standards that a product must meet to be accepted.
