Mechanical Systems 2

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






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






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






4. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.






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






6. A swing back and forth at a regular rate.






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






8. A wheel with a grooved rim to guide a rope or chain that runs along the groove; used to transmit or change direction of force.






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






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






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






12. Energy is transferred from one plan to another - and no energy is changed or converted.






13. The that has a handle because of a motoe or person turning it.






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






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






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






17. A twisting force.






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






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






20. A small cogwheel that engages or is engaged by a larger cogwheel.






21. The point of the lever that does not move.






22. Work= force x distance






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






24. The results of the operation of any system.






25. The transmission of power between shafts by means of a belt connecting pulleys on the shafts.






26. Measurement for work






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






28. The ability to do work.






29. A push or pull on an object.






30. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.






31. The distance in a strait line from the center of a circle to the circle circumference






32. The application of force that moves an object a certain distance.






33. The ratio of the force produced by a machine or system (the load) to the force applied to the machine or system.






34. The energy of motion.






35. A way to measure stuff.






36. 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.

37. One of a pair of gears used to connect two shafts whose axes intersect.






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






39. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.






40. Movement in a straight line.






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






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






43. A pear- shaped disk with an off- center pivot point - used to change rotating motion into reciprocating motion.






44. A threaded shaft used to convert rotary movement to linear movement.






45. The gear being turned buy the driver gear






46. A machine used for raising or moving liquids.






47. The work done by a machine as the output force acts through the output distance






48. Circular movement.
