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. 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.






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






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






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






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






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






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






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






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






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






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






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






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






14. Someone who starts a business.






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






16. A resource that is entered into a system.






17. The splitting of the nucleus of an atom.






18. 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.'






19. 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.






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






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






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






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






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






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






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






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






28. 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.






29. 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.






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






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






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






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






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






35. A method of obtaining energy from waste products






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






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


38. 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.






39. The formal rules that guide the design process.






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






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






42. The basic framework of a system






43. Creating things through the process of planning.






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






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






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






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






48. Energy in motion.






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






50. Restriction or limit placed on a product.
