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






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






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






4. Energy in motion.






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






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






7. 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.






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






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






10. 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.






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






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






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






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






15. A resource that is entered into a system.






16. A method of obtaining energy from waste products






17. 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.






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






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






20. 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.






21. The capacity to do work or exert effort.






22. 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.






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






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






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






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






27. Creating things through the process of planning.






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






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






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






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






32. 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.






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






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






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






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






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


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






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






40. The splitting of the nucleus of an atom.






41. The basic framework of a system






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






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






44. Restriction or limit placed on a product.






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






46. A popular movement.






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






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






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






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