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 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.






2. Stored energy or energy at rest.






3. A method of obtaining energy from waste products






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






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






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






7. The basic framework of a system






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






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






10. 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.






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






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






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






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






16. The splitting of the nucleus of an atom.






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






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






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






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. The superimposition of sine waves on electromagnetic carrier waves.






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






23. Restriction or limit placed on a product.






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






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






26. 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.






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






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






29. 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.






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






31. Creating things through the process of planning.






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






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






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






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






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






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






38. 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.






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






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






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






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






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






44. Energy in motion.






45. 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.






46. The capacity to do work or exert effort.






47. 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.






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






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






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