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






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






3. The splitting of the nucleus of an atom.






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






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






6. Creating things through the process of planning.






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






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






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






10. Stored energy or energy at rest.






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






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






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






14. 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.






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






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






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






18. The basic framework of a system






19. 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.






20. The formal rules that guide the design process.






21. 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.






22. A method of obtaining energy from waste products






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






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






25. 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.






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






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






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






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






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






31. Energy in motion.






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






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






34. A popular movement.






35. 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.






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






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






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






39. 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.






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






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






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






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






44. Restriction or limit placed on a product.






45. Someone who starts a business.






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






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






48. 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.






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






50. 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.
