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






2. A popular movement.






3. A resource that is entered into a system.






4. 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.






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






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






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






8. Energy in motion.






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






10. A method of obtaining energy from waste products






11. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






12. Creating things through the process of planning.






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






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






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






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






17. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






18. The capacity to do work or exert effort.






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






20. The basic framework of a system






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






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






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






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






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






26. The capacity to do work or exert effort.






27. 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.






28. 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.






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






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






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


32. The splitting of the nucleus of an atom.






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






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






35. 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.






36. The formal rules that guide the design process.






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






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






39. Someone who starts a business.






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






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






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






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






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






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






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






47. 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.






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






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






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