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






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






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






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






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






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






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






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






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






10. A method of obtaining energy from waste products






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






12. The capacity to do work or exert effort.






13. Someone who starts a business.






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






15. 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.






16. A popular movement.






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






18. 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.






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






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






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






22. The basic framework of a system






23. A resource that is entered into a system.






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






25. The splitting of the nucleus of an atom.






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






27. Energy in motion.






28. Creating things through the process of planning.






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






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






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






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






33. 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.






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






35. 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.






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






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






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






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






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






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






42. 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.






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






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






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






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






47. The formal rules that guide the design process.






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






49. Stored energy or energy at rest.






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