Simple Machines
Across
- 3. a wheel to move a greater distance with less effort.
- 5. The fixed balancing point of a lever. An example of a fulcrum is
- 7. machines A machine in which two or more simple
- 9. A simple machine that applies force to a fixed bar
- 10. wood and rocks and raising heavy objects.
- 16. force The force exerted to do work.
- 17. A simple machine that consists of a rigid bar turning on a fixed point
- 18. an axle, which that is attached to a wheel.This force is multiplied and
- 19. inclined planes.
- 21. Gravity and friction can be considered resistance forces.
- 23. in combination to increase applied force in order to make work easier.
- 24. A simple machine that tapers to a thin edge and can be used for
Down
- 1. machines Devices used to reduce the effort force needed to do
- 2. advantage (MA) The number of times that a machine multiplies
- 4. have been combined. Pliers are an example of a compound
- 6. that uses a lever and a wheel-and-axle.
- 8. force The push or pull on an object that works against effort
- 9. around it.
- 11. plane A simple machine that uses a ramp to reduce the effort
- 12. effort force.The greater the MA, the less effort force is required.
- 13. wheel that can turn to reverse the direction of a force. Pulleys are
- 14. A simple machine consisting of a cord or rope wrapped around a

- 20. and tackle A compound machine consisting of fixed and
- 21. by increasing the distance. A wedge and a screw are examples of
- 22. A simple machine consisting of a central core with a groove
