Down
- 1. A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or for tightening by being driven into something
- 2. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force
- 4. Ratio of distance traveled by the applied effort and resistance force within a system
- 5. Distance between adjacent threads in a screw
- 7. Two different sized circular objects that are attached together and turn as one
- 10. A continuous band of tough flexible material used to transmit motion and power within a pulley system
- 11. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity
- 12. A type of lever that is a wheel with a groove in its rim, which is used to change the direction or multiply a force exerted by a rope or cable
- 14. An external force applied to an object
- 17. Impeding effect exerted by one material object on another
- 20. 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 and turning at a third on a fulcrum
- 21. A circular toothed object used to transfer rotary motion and torque through interlocking teeth
- 25. A toothed wheel whose teeth engage the links of a chain
