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 circuit in which electricity flows along more than one path.






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






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






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






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






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






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






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






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






10. Creating things through the process of planning.






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






12. The capacity to do work or exert effort.






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






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






15. Restriction or limit placed on a product.






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






17. The formal rules that guide the design process.






18. Stored energy or energy at rest.






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






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






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






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






23. 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.






24. 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.'






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






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






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






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


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






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 group of people working together to accomplish a common goal.






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






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






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






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






37. A method of obtaining energy from waste products






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






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






40. The basic framework of a system






41. 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.






42. The splitting of the nucleus of an atom.






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






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






45. 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.






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






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






48. 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.






49. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






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.
