Across
- 2. movable bar that pivots on a fulcrum attached to or positioned on or across a fixed point.
- 6. also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load
- 7. quantity that is described by magnitude but lacks direction
- 8. quantity with magnitude and direction.
- 11. a machine consisting of two or more simple machines operating together.
- 12. a simple machine that consists of two inclined planes, giving it a thin end and thick end.
- 13. any of several devices with few or no moving parts that are used to modify motion and the magnitude of force in order to perform work.
- 15. physical measurement of the amplification of force achieved by using a tool, mechanical device, or machine system
Down
- 1. amount of reduction from the ideal to the actual mechanical advantage.
- 3. a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.
- 4. the measure of force amplification of a device with the assumption that its components do not flex, there is no friction, and there is no wear. It is calculated using the physical dimensions of the device and defines the maximum performance the device can achieve.
- 5. the force or the component of a force which a surface exerts on an object with which it is in contact, and which is perpendicular to the surface.
- 9. force when stretched or under applied force; in opposite direction to the force applied on it.
- 10. the force that opposes the motion of an object and which acts parallel to the surface.
- 14. mechanism that converts rotational motion to linear motion and rotational force to linear force.
