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






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






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






4. A popular movement.






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






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






7. The splitting of the nucleus of an atom.






8. Energy in motion.






9. 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.






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






11. 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.






12. The capacity to do work or exert effort.






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






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






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






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






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






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






19. 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.






20. 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.






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






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






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






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






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






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






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






28. Stored energy or energy at rest.






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






30. 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.






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






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






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






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






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






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






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






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






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






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






41. A method of obtaining energy from waste products






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






43. A resource that is entered into a system.






44. 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.






45. Restriction or limit placed on a product.






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






47. Someone who starts a business.






48. The capacity to do work or exert effort.






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






50. The basic framework of a system
