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






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






3. 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.






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






5. A unit that collects waves and decodes information contained within those waves.






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






7. 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.






8. The capacity to do work or exert effort.






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


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






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






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






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






14. 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.






15. A circuit in which electricity flows along more than one path.






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






17. 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.






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






19. 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.






20. Creating things through the process of planning.






21. The formal rules that guide the design process.






22. The use of lasers to record realistic images of three- dimensional objects.






23. A popular movement.






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






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






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






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






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






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






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






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






32. Stored energy or energy at rest.






33. The splitting of the nucleus of an atom.






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






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






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






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






38. A method of obtaining energy from waste products






39. The basic framework of a system






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






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






42. Current flow in which electrons move in only one direction.






43. 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.






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






45. Restriction or limit placed on a product.






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






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






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






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






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