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 basic framework of a system






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






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






4. 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.






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






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






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






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






9. The splitting of the nucleus of an atom.






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


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






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






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






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






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






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






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






18. A popular movement.






19. A resource that is entered into a system.






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






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






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






23. 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.






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






25. The formal rules that guide the design process.






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






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






28. The capacity to do work or exert effort.






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






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






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






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






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






34. 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.






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






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






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






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






39. The capacity to do work or exert effort.






40. Stored energy or energy at rest.






41. 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.






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






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






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






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






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






47. Creating things through the process of planning.






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






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






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