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.

25. A pulley supported by attachment to something that does not move - such as a ceiling - wall - or tree.






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






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






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






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






30. A twisting force.






31. 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.






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






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

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






36. Movement in a straight line.






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






38. 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.
