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






2. 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.






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






4. The energy of motion.






5. Circular movement.

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






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






9. A machine used for raising or moving liquids.






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






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






12. A rotating wheel- like device with teeth around the rim.






13. 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.

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






16. The science of designing gone or work environments that best suit the human body in it various dimensions.






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






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






19. The ability to do work.






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






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






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






23. The gear which transmits power and motion to the rest of the system. The input gear.






24. Movement in a straight line.






25. A way to measure stuff.






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






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






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






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






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






32. A twisting force.






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






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






35. Acts on a certain area.






36. The gear being turned buy the driver gear






37. 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.






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






39. A push or pull on an object.






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






41. A combo of several pulleys working together.






42. The member of a pair of gears to which motion and power are transmitted by the other. The output gear.






43. A system in which a gas - such as air - transmits a force exerted on gas in an enclosed space.






44. A back and forth movement.






45. Work= force x distance






46. 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.
