Across
- 2. The type of lever where the fulcrum is placed between the load and the effort, as in the seesaw, crowbar, and balance scale.
- 3. The type of lever where the load is between the effort and the fulcrum.
- 4. One of the simple machines, a plane surface inclined to the horizon, or forming with a horizontal plane any angle but a right angle.
- 5. 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.
- 6. Strength or power exerted upon an object.
- 8. The ratio of output force to the input force applied to a mechanism.
- 10. The type of lever where the effort is placed between the load and the fulcrum.

- 20. Energy of vibrations.
- 22. Input force is the initial force used to get a machine to begin working.
- 23. 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.
- 24. 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.
- 25. 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.
