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






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






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






4. A method of obtaining energy from waste products






5. 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.






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






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






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






9. A resource that is entered into a system.






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






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






12. Creating things through the process of planning.






13. 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.






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






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






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






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






18. 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.






19. Someone who starts a business.






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






21. The basic framework of a system






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






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






24. 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.






25. The formal rules that guide the design process.






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






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






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






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






30. Restriction or limit placed on a product.






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






32. 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.






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






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






35. 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.






36. Energy in motion.






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






38. A popular movement.






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






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






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






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






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






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






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






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






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






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






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






50. 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.
