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 circuit in which electricity flows along more than one path.






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






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






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






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






6. Someone who starts a business.






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






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






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






10. A popular movement.






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






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






13. Creating things through the process of planning.






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






15. The splitting of the nucleus of an atom.






16. 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.






17. 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.






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






19. The formal rules that guide the design process.






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






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






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






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






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






25. 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.






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






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






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


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






30. The capacity to do work or exert effort.






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






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






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






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






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






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






37. The capacity to do work or exert effort.






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






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






40. 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.






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






42. 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.






43. A method of obtaining energy from waste products






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






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






46. Energy in motion.






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






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






49. 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.






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