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 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.






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






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






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






5. 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.






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






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






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






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


10. 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.






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






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






13. 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.






14. The capacity to do work or exert effort.






15. Someone who starts a business.






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






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






18. A method of obtaining energy from waste products






19. Creating things through the process of planning.






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






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






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






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






24. 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.'






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






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






27. The capacity to do work or exert effort.






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






29. The splitting of the nucleus of an atom.






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






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






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






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






34. Stored energy or energy at rest.






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






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






37. 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.






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






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






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






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






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. A resource that is entered into a system.






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






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






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






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






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






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






50. A popular movement.
