UA2 scienc 8 section 1.0
Across
- 1. Smaller group of parts within a complex machine that performs a specific function
- 6. Pair of wheels with teeth that interlink; when they rotate together, one gearwheel transfers turning motion and force to the other
- 8. Simple machine made up of a flat surface, such as a board, at an angle to another flat surface, such as the ground or a table top; ramp
- 10. Tool or device made up of one basic machine
- 11. System in which simple machines all work together; parts of a complex machines that have just one function are called subsystems and often contain a simple machine
- 12. Simple machine that consists of a cylinder with a groove cut in a spiralon the outside
- 13. simple machine made up of two wheels of different diameters that turn together; a longer motion on the wheel produces a shorter but more powerful motion at the axel
Down
- 2. A group of parts that work together to perform a general function, forming a complex machine
- 3. Special type of linkage for transferring from the engine to the wheels in a large vehicles such as cars and trucks
- 4. Simple machine made up of a wire, rope, or cable moving on a grooved wheel; may be made up of one or many wheels; can be fixed in place or moveable
- 5. Simple machine made up of rigid bar or plank that rotates on a fixed object called a pivot or fulcrum
- 7. Belt or chain transfer from energy from an energy source to an object
- 9. Simple machine that looks like an inclined plane, but is a forced into an object
