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






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






3. 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.






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






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






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






7. Energy in motion.






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






9. 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.






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






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






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






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






14. The capacity to do work or exert effort.






15. 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.






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






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






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






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






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






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






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






23. Someone who starts a business.






24. Stored energy or energy at rest.






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






26. Restriction or limit placed on a product.






27. Creating things through the process of planning.






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






29. A resource that is entered into a system.






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






31. A method of obtaining energy from waste products






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






33. The capacity to do work or exert effort.






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






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






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






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






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






39. 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.






40. The splitting of the nucleus of an atom.






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






42. The formal rules that guide the design process.






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


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






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






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






47. 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.






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






49. The unlawful acquisition of some one's personal information for use without their consent.






50. A popular movement.
