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 computers in each stage of the design process.






2. 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.






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






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






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






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






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






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






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






10. A resource that is entered into a system.






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






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






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






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






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






16. The splitting of the nucleus of an atom.






17. A popular movement.






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






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






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






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






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






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






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






25. 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.'






26. Stored energy or energy at rest.






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






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






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






30. Restriction or limit placed on a product.






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






32. 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.






33. 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.






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






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






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






37. 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.






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






39. 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.






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






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






42. The basic framework of a system






43. 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.






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






45. Someone who starts a business.






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






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






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






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






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