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 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.






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






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






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






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






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






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






8. The formal rules that guide the design process.






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






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


11. The splitting of the nucleus of an atom.






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






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






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






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






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






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






18. The capacity to do work or exert effort.






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






20. 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.






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






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






23. A method of obtaining energy from waste products






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






25. 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.






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






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






28. Restriction or limit placed on a product.






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






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






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






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






33. 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.






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






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






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






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






38. 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.






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






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






41. 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.'






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






43. Someone who starts a business.






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






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






46. A resource that is entered into a system.






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






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






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






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