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 a message travels from the sender to receiver.






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






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






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






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






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






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






8. A resource that is entered into a system.






9. The capacity to do work or exert effort.






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






11. The splitting of the nucleus of an atom.






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






13. 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.






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






15. Restriction or limit placed on a product.






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






17. 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.






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






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






20. 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.






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






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






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






24. Creating things through the process of planning.






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






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






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. Stored energy or energy at rest.






29. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






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






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






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






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






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






35. 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.






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






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






38. 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.






39. The formal rules that guide the design process.






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






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






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






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


44. Energy in motion.






45. Someone who starts a business.






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






47. 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.






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






49. 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.






50. The basic framework of a system
