Across
- 4. A first-class lever that has an axle attached to a supporting structure and changes the direction of force.
- 7. rotate together as a simple lever to lift or move a load. The effort force can be applied to either and transfers a rotational force from one to the other.
- 10. when an object is translated, or moved linearly, in one direction and then back along the same path in the opposite direction until it returns to its starting point; the cycle is then repeated.
- 15. An external force applied to an object.
- 16. when an object moves in a straight line from one point in space to another.
- 18. The energy transferred when a force F is applied to an object moving through a distance d.
- 20. A representation of a real-world situation or system using mathematical concepts and language.
- 21. a rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second point and turning on a fulcrum at a third.
Down
- 1. a wheel with a groove in its rim that is used to change the direction and/or magnitude of a force exerted by a rope
- 2. A machine made up of two or more simple machines.
- 3. Fixed and movable pulleys in combination that provide mechanical advantage and a change of direction for effort force.
- 5. The ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.
- 6. when an object moves back and forth in a reciprocating manner, but with elements of rotational motion like swinging.
- 8. Impeding effect exerted by one material object on another.
- 9. The greatness of size or amount.
- 11. A rotating or sliding part in a mechanism used especially to transform rotational motion to linear motion or vice versa.
- 12. rotation around a fixed axis.
- 13. is made of two components: an inclined plane wrapped around a cylinder, forming the path and pitch, and a wheel and axle used to create rotary motion.
- 14. is a flat surface set at an angle, or incline, with no moving parts. It allows for objects to be lifted by pushing or pulling the load.
- 17. A pulley with an axle in a movable block that is supported by two parts of the same rope. In a movable pulley, force directions stay constant.
- 19. functions as a moving inclined plane that tapers to a thin edge and is used for splitting or raising heavy bodies, or for tightening by being driven into something.
