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 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.






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






3. The formal rules that guide the design process.






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






5. 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.






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






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


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






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






10. 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.






11. Someone who starts a business.






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






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






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






15. 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.






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






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






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






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






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






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






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






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






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






25. Stored energy or energy at rest.






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






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






28. The capacity to do work or exert effort.






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






30. 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.






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






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






33. A resource that is entered into a system.






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






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






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






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






38. Energy in motion.






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






40. Restriction or limit placed on a product.






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






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






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






44. 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.






45. Creating things through the process of planning.






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






47. 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.






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






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






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