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






2. The ratio of the speed of the driving member of a gear train to that of the driven member.






3. The ability to do work.






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






5. Stored energy






6. Measurement for work






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






8. 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.

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






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






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






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

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






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






44. A common workplace disorder causing numbness and pain in the thumb and first three finger.






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






46. 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.
