Across
  1. 3. The energy of motion.
  2. 6. The force that is exerted from the input force to create motion of the resisting object.
  3. 8. A pulley that is a combination of fixed and a movable pulleys forms a block and tackle.
  4. 10. Input force is the initial force used to get a machine to begin working.
  5. 12. Accomplishment of or ability to accomplish a job with a minimum expenditure of time and effort.
  6. 16. The type of lever where the load is between the effort and the fulcrum.
  7. 17. The type of lever where the effort is placed between the load and the fulcrum.
  8. 19. The energy obtained if something is stretched or compressed and has the ability to bounce back.
  9. 21. A threaded cylindrical pin or rod with a head at one end, engaging a threaded hole and used either as a fastener or as a simple machine for applying power.
  10. 23. A mechanical device that changes the direction or magnitude of a force.
  11. 26. A rigid bar that pivots about one point and that is used to move an object at a second point by a force applied at a third.

  1. 1. One of the simple machines, a plane surface inclined to the horizon, or forming with a horizontal plane any angle but a right angle.
  2. 2. Energy of vibrations.
  3. 4. Exertion or effort directed to produce or accomplish something; labor; toil.
  4. 5. The ratio of output force to the input force applied to a mechanism.
  5. 7. Strength or power exerted upon an object.
  6. 9. Work done or energy transferred per unit of time.
  7. 11. A pulley that has an axle mounted in bearings attached to a supporting structure.
  8. 13. The energy stored in chemical bonds.
  9. 14. A piece of hard material with two principal faces meeting in a sharply acute angle, for raising, holding, or splitting objects by applying a pounding or driving force, as from a hammer.
  10. 15. Equal to the work per unit mass that is done by the force of gravity to move an object to a fixed reference location.
  11. 18. The type of lever where the fulcrum is placed between the load and the effort, as in the seesaw, crowbar, and balance scale.
  12. 20. A wheel, with a grooved rim for carrying a line, that turns in a frame or block and serves to change the direction of or to transmit force.
  13. 22. A simple machine consisting, in its typical form, of a cylindrical drum to which a wheel concentric with the drum is firmly fastened.
  14. 24. A pulley that has an axle in a movable block.
  15. 25. An exertion of power.
