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






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






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






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






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






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






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






8. The basic framework of a system






9. The capacity to do work or exert effort.






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






11. The formal rules that guide the design process.






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






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






14. 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.






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






16. The splitting of the nucleus of an atom.






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






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






19. 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.






20. Someone who starts a business.






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






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






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






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






25. 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.






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






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






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






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






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






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






32. Creating things through the process of planning.






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






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






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






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






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






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






39. A resource that is entered into a system.






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






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






42. 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.






43. 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.






44. A method of obtaining energy from waste products






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






46. Energy in motion.






47. Restriction or limit placed on a product.






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






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






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