Simple Machines
Across
- 4. A simple machine that is a smooth, flat surface tilted at an angle, like a ramp
- 7. A simple machine that is a disk or a ring (the wheel)attached to a rod (the axel so that both turn together
- 9. A combination of two or more simple machines, such as a bicycle
- 11. A simple machine that is a rigid bar that turns on a fixed point
- 13. A simple machine that is an incline plane wrapped around a column
- 15. One of 6 simple tools that make work easier, including inclined planes, levers, wedges, screws, pulleys, and wheels and axels
- 16. something being moved by a machine
- 19. The force that tends to keep a load from moving
- 20. A pulley consisting of fixed pulley(s) and moveable pulley(s)
- 22. A pulley that moves along with the load
- 24. A simple machine that uses a grooved wheel and a rope to move a load
- 25. the distance between each turn of the thread on a screw
Down
- 1. The fixed point on which a lever turns
- 2. A lever whose fulcrum is opposite the load, with the effort between them, like tweezers
- 3. A pulley that does not move; the load is attached to a rope that moves over the pulley
- 5. Two or more pulleys used together to move a load
- 6. A simple machine that is two incline planes back to back
- 8. A lever whose fulcrum is between the effort and the load, like a seesaw
- 10. A force that resists motion, caused by surfaces rubbung together
- 12. A lever whose fulcrum is opposite the effort, with the load between them, like a wheelbarrow
- 14. A tool or device that makes work easier
- 17. the tiny ramp that spirals around the shaft of a screw
- 18. Moving a load over a distance
- 21. A push or pull that makes something move
