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 path by which electric current or pulses flow.






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






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. Creating things through the process of planning.






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






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






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






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






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






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






11. A method of obtaining energy from waste products






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






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






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






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






16. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






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






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






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






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






21. The formal rules that guide the design process.






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






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






24. The capacity to do work or exert effort.






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






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






27. The capacity to do work or exert effort.






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






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






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






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






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


33. The splitting of the nucleus of an atom.






34. Energy in motion.






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






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






37. A resource that is entered into a system.






38. Someone who starts a business.






39. 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.






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






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






42. The basic framework of a system






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






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






45. 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.






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






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






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






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






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