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






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






3. Restriction or limit placed on a product.






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






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






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






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






8. 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.






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






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






11. A popular movement.






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






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






14. Someone who starts a business.






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






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






17. The capacity to do work or exert effort.






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






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






20. Creating things through the process of planning.






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






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






23. 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.






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






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






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






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






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






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






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






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






32. 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.






33. The formal rules that guide the design process.






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






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






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






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






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






39. The splitting of the nucleus of an atom.






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






41. 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.






42. 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.'






43. A resource that is entered into a system.






44. Stored energy or energy at rest.






45. 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.






46. The capacity to do work or exert effort.






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






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






49. A method of obtaining energy from waste products






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