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. 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.






3. 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.






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






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






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


7. The splitting of the nucleus of an atom.






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






9. 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.'






10. Creating things through the process of planning.






11. Stored energy or energy at rest.






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






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






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






15. 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.






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






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






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






19. 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.






20. The capacity to do work or exert effort.






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






22. The formal rules that guide the design process.






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






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






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






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






27. Restriction or limit placed on a product.






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






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






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






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






32. A popular movement.






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






34. The capacity to do work or exert effort.






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






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






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






38. 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.






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






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






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






42. 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.






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






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






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






46. 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.






47. A method of obtaining energy from waste products






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






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






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