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






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






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






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






5. The basic framework of a system






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


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






8. A method of obtaining energy from waste products






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






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






11. A resource that is entered into a system.






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






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






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






15. 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.






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






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






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






19. The capacity to do work or exert effort.






20. 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.






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






22. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






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






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






33. Stored energy or energy at rest.






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






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






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






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






38. 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.






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






40. A popular movement.






41. Someone who starts a business.






42. The formal rules that guide the design process.






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






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






45. Creating things through the process of planning.






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






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






48. 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.






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






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