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






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






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






4. A method of obtaining energy from waste products






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






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






7. 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.






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






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






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






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


12. The basic framework of a system






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






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






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






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






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






18. 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.






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






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






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






22. The formal rules that guide the design process.






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






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






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






26. 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.






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






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






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






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






31. Stored energy or energy at rest.






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






33. 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.






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






35. 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.






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






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






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






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






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






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






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






43. 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.






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






45. A resource that is entered into a system.






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






47. Creating things through the process of planning.






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






49. 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.






50. 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.
