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






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






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






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






6. Stored energy or energy at rest.






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






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






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






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






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






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






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






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






15. A popular movement.






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






17. 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.






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






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






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






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






22. The basic framework of a system






23. 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.






24. The capacity to do work or exert effort.






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






26. The formal rules that guide the design process.






27. The capacity to do work or exert effort.






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






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






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


31. Restriction or limit placed on a product.






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






33. Energy in motion.






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






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






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






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






38. Someone who starts a business.






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






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






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






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






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






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






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






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






47. 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.






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






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