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






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






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






4. Someone who starts a business.






5. A popular movement.






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






7. The formal rules that guide the design process.






8. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






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






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






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






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






13. Restriction or limit placed on a product.

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






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






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






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






19. 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.






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






21. The basic framework of a system






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






23. The capacity to do work or exert effort.






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






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






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






27. 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.






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






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






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






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






32. 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.






33. The capacity to do work or exert effort.






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






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






36. Creating things through the process of planning.






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






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






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






40. The splitting of the nucleus of an atom.






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






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






43. 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.






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






45. A resource that is entered into a system.






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






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






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






49. The number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.






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