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






2. Stored energy or energy at rest.






3. 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.






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


5. 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.






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






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






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






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






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






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






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






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






14. 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.






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






16. A resource that is entered into a system.






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






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






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






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






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






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






23. A method of obtaining energy from waste products






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






25. Creating things through the process of planning.






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






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






28. 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.






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






30. 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.






31. The formal rules that guide the design process.






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






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






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






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






36. 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.






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






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






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






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






41. 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.






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






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






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






45. Restriction or limit placed on a product.






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






47. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






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






49. The capacity to do work or exert effort.






50. The capacity to do work or exert effort.
