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






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






3. Restriction or limit placed on a product.






4. The capacity to do work or exert effort.






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






6. The capacity to do work or exert effort.






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






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






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






10. The formal rules that guide the design process.






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






12. The splitting of the nucleus of an atom.






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






14. The use of a computer system to produce technical drawings and/or design a product.






15. The basic framework of a system






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






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






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






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






21. Energy in motion.






22. A method of obtaining energy from waste products






23. Creating things through the process of planning.






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






25. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






26. 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.






27. 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.






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






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






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






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






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






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






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






35. 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.






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






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






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






39. Stored energy or energy at rest.






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






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






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






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






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






45. 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.






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






47. 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.






48. 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.






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






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