Simple Machines
Across
- 3. This simple machine uses a cylindrical object to rotate around its central axis, reducing the force needed to perform a task.
- 4. Bearing This simple machine reduces friction and is often used in rolling objects.
- 6. Pulley This simple machine combines multiple pulleys to reduce the force needed to lift an object.
- 10. Lever This type of lever has the effort force positioned between the load and the fulcrum.
- 12. This part of a lever is the point on which the lever pivots.
- 13. This simple machine is often used in door hinges to allow smooth movement.
- 16. System This simple machine is used in cranes to lift heavy materials to greater heights with ease.
- 17. Lever This type of lever has the fulcrum positioned between the load and the effort force.
- 19. This simple machine is a combination of two inclined planes and is used to split or separate objects.
- 20. This simple machine consists of a circular object that rolls around a central axis.
Down
- 1. Train This simple machine consists of two or more gears working together to increase mechanical advantage.
- 2. Lever This type of lever has the load positioned between the fulcrum and the effort force.
- 5. This simple machine consists of a bar that pivots on a fixed point called a fulcrum.
- 7. Wedge This simple machine uses slanted surfaces that move in opposite directions to split an object apart.
- 8. and Axle This simple machine is made of a circular object attached to a rod and is used to magnify force.
- 9. This simple machine is a spirally grooved cylinder used to hold objects together or lift materials.
- 11. This simple machine is a wheel with a grooved rim through which a rope passes to lift objects.
- 14. Plane This simple machine is a flat surface set at an angle to help move objects up or down.
- 15. and Tackle This simple machine uses a wheel and a rope to lift heavy objects with less effort.
- 18. This simple machine is used to fasten two objects together and has a spiral shape.
