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






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






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






4. 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.






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






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






7. Energy in motion.






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






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






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






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






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






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






15. The splitting of the nucleus of an atom.






16. 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.






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






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






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






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






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

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






23. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






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






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






35. Restriction or limit placed on a product.






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






38. The formal rules that guide the design process.






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






40. 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.






41. 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.






42. A method of obtaining energy from waste products






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






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






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






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






47. A resource that is entered into a system.






48. A popular movement.






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






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