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 splitting of the nucleus of an atom.






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






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






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






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






8. 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.






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






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






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






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






13. 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.






14. The capacity to do work or exert effort.






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






16. Energy in motion.






17. 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.






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






19. A resource that is entered into a system.






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






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






22. 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.






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






24. A popular movement.






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






26. 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.






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






28. 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.






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






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






31. 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.






32. The formal rules that guide the design process.






33. Creating things through the process of planning.






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






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






36. A method of obtaining energy from waste products






37. The capacity to do work or exert effort.






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






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






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






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


42. The unlawful acquisition of some one's personal information for use without their consent.






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






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






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






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






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






48. The basic framework of a system






49. Restriction or limit placed on a product.






50. 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.
