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






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


3. Restriction or limit placed on a product.






4. 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.






5. 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.






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






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






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






9. A resource that is entered into a system.






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






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






12. 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.






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






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






15. The capacity to do work or exert effort.






16. 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.






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






18. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






19. The formal rules that guide the design process.






20. 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.






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






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






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






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






25. Stored energy or energy at rest.






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






27. Creating things through the process of planning.






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






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






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






31. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






41. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






49. 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.






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