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 path by which electric current or pulses flow.






2. 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.






3. 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.






4. 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.






5. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






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






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






8. 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.






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


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






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






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






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






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






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






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






17. The formal rules that guide the design process.






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






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






20. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






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






22. The capacity to do work or exert effort.






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






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






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






26. Restriction or limit placed on a product.






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






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






29. Creating things through the process of planning.






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






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






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






33. 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.






34. The splitting of the nucleus of an atom.






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






37. The basic framework of a system






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






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






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






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






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






43. Energy in motion.






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






45. Stored energy or energy at rest.






46. 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.






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






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






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






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