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.

5. A gear between the driver and the driven gear used to change rotational direction.






6. A device used to regulate the flow of a liquid in a hydraulic system.






7. The ratio of the useful work or energy provided by a machine or system with the actual work or energy supplied to the machine or system.






8. A combination of fixed and movable pulleys - may be used to list very heavy or awkward loads.

33. A machine used for raising or moving liquids.






34. A twisting force.






35. A gear with teeth that fits into the links of a chain.






36. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.






37. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.






38. The force acting perpendicular to a certain surface area.






39. A secondary or subordinate system that is part if a larger system.

45. A mechanical system that uses a liquid under pressure in a close system to raise heavy objects.






46. The ability to do work.






47. A law stating that when pressuer is exerted on on part of a fluid - the same pressure is transmitted unchanged to all parts of the fluid - no matter what the shape of the container holding fluid. EX: water balloon.
