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






2. Creating things through the process of planning.






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






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






5. A method of obtaining energy from waste products






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






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






8. 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.'






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






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






11. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






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






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






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






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






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






24. 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.






25. 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.






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






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






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






29. The formal rules that guide the design process.






30. Stored energy or energy at rest.






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






32. 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.






33. The capacity to do work or exert effort.






34. The capacity to do work or exert effort.






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






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






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






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






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






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






41. Energy in motion.






42. 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.






43. Someone who starts a business.






44. Restriction or limit placed on a product.






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






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






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






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






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






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