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.

2. A machine consisting of a small cylinder - a crank or handle - on a cable. Winch can be used to lift or pull things






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






4. 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.






5. The work done on a machine as the input force acts through the input distance






6. Opposite in position - direction - order or effect.






7. A machine consisting of a bar that is free to rotate around a fixed point - changing the amount of force that must be exerted to move an object.






8. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.






9. A lever in which the effort is applied between the fulcrum and the load.






10. A system having a boundary that separates it from it surroundings.






11. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.

21. The results of the operation of any system.






22. A back and forth movement.






23. Something put into a system - such as resources - in order to achieve a result.






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






25. The weight of an object that is is moved or lifted by a machine - or resistance to movement that a machine must overcome

27. A machine consisting of two turning objects attached to each other at thier centers. One object to turn






28. A machine used for raising or moving liquids.






29. The realtioship between the speed of rotation of a smaller gear and a larger gear = number of driven gear teeth / Number of following gear teeth.






30. A lever in which the load is between the fulcrum and the effort.






31. A joint that allows connected shafts to spin freely while permitting a change in direction.






32. 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.
