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 a single path to more than one device.






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






3. 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.






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






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






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






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






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






9. 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.






10. A method of obtaining energy from waste products






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






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






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






14. 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.






15. 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.






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






17. Energy in motion.






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






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






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






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






22. 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.






23. 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.






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






25. 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.






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


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






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






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






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






31. The basic framework of a system






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






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






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






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






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






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






38. Stored energy or energy at rest.






39. A popular movement.






40. Restriction or limit placed on a product.






41. Someone who starts a business.






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






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






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






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






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






47. The splitting of the nucleus of an atom.






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






49. Creating things through the process of planning.






50. 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.
