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






2. The capacity to do work or exert effort.






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






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






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






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






7. A method of obtaining energy from waste products






8. 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.






9. The splitting of the nucleus of an atom.






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






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






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






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






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






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






16. Creating things through the process of planning.






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






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






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






20. 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.






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






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






23. Energy in motion.






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






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






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






27. 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.






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






29. The formal rules that guide the design process.






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






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






32. 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.






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






34. Someone who starts a business.






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






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






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






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






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






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

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






42. The capacity to do work or exert effort.






43. 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.'






44. 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.






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






46. The basic framework of a system






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






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






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






50. Restriction or limit placed on a product.
