Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 30 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 group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






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






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






4. The basic framework of a system






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






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






7. The capacity to do work or exert effort.






8. 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.






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






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






11. A popular movement.






12. A method of obtaining energy from waste products






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






14. 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.






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






16. Energy in motion.






17. Someone who starts a business.






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






19. A resource that is entered into a system.






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






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






22. 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.






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






24. 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.






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






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






27. Restriction or limit placed on a product.






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






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






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






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






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






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






34. 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.






35. 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.






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






37. The capacity to do work or exert effort.






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






39. Creating things through the process of planning.






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






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






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






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






44. 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.






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






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






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






48. 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.






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






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