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. 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.






2. 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.






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






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






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






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






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






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






9. A resource that is entered into a system.






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


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






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






13. Stored energy or energy at rest.






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






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






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






17. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Creating things through the process of planning.






35. 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.






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






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






38. 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.






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






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






41. A popular movement.






42. The capacity to do work or exert effort.






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






44. Restriction or limit placed on a product.






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






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






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






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






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






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