Across
- 4. machine Combination of two or more simple machines.
- 8. The ratio of output work to input work.
- 9. machine A machine that does work with only one movement.
- 10. and axle machine with a wheel attached to a central shaft (axle) that rotates together.
- 11. machine with a rigid bar that pivots around a fixed point (fulcrum) to lift, move, or multiply force, making work easier by changing the direction or amount of effort needed.
Down
- 1. inclined plane (ramp) wrapped around a cylinder, converting rotational force (torque) into strong linear force to fasten objects, lift them, or create holes, making work easier by trading distance for force.
- 2. plane machine, like a ramp, that's a flat, sloped surface connecting a lower level to a higher one, making it easier to lift heavy objects by trading a smaller force over a longer distance for the large force needed for a direct vertical lift.
- 3. A device that changes the force or increases the motion from work.
- 5. advantage: The ratio of output force to input force.
- 6. machine consisting of a wheel with a groove for a rope or cable, used to change the direction of a force or to amplify it, making it easier to lift or move heavy objects.
- 7. two inclined planes back-to-back, used to split, lift, or hold objects by converting a force applied to its thick end into a larger, perpendicular force that pushes outwards, making.
- 10. Force applied through a distance.
