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 a single path to more than one device.






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






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






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






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






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






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






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






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






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






11. A resource that is entered into a system.






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






13. The capacity to do work or exert effort.






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






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






16. 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.






17. 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.






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


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






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






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






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






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






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






25. The formal rules that guide the design process.






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






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






28. A method of obtaining energy from waste products






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






30. Energy in motion.






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






32. 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.






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






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






35. The basic framework of a system






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






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






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






39. The capacity to do work or exert effort.






40. Restriction or limit placed on a product.






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






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






43. Stored energy or energy at rest.






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






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






46. Creating things through the process of planning.






47. 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.






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






49. 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.






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