Across
- 5. force a machine applies to an object
- 6. belt or chain to transfer energy source to an object
- 7. special type of linkage for transferring the energy from the engine to the wheels in large vehicles such as cars and trucks
- 9. simple machine made up of two wheels of different diameters that turn together; a longer motion at the axle
- 12. simple machine made up of a rigid bar or plank that rotates on a fixed objected called a pivot or fulcrum
- 16. system that uses a liquid under pressure to move loads; device that uses liquids in a confined space to transfer force; works according to Pascal's law
- 17. force applied to operate a machine
- 19. machine tool or device made up of one basic machine
- 21. a person who repairs and maintains machinery
- 22. measure of how the speed of the object is affected by a machine; calculated by dividing the input distance by the output distance
- 23. plane 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
- 24. simple machine made up of a wire, rope or cable moving on a grooved wheel; maybe made up of one or many wheels; can be fixed in place or movable
Down
- 1. a group of parts that work together to preform a general function, forming an complex machine
- 2. a machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer
- 3. smaller group of parts within a complex machine that preforms a specific function
- 4. amount by which a machine can multiply a force; calculated by dividing the output force by the input
- 8. simple machine that consists of a cylinder with a groove cut in a spiral on the outside
- 10. measurement of how well a machine or device uses energy; can be calculated by dividing mechanical advantage by speed radio or dividing work output by work input
- 11. when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid; an enclosed liquid transmits pressure equally in all directions
- 13. purpose, planning or intention that exists or is thought to exist behind an action, fact or material object
- 14. purpose or task
- 15. done when a force acts on an object to make the object move; calculated by multiplying force times distance
- 18. measure of the amount of force applied to a given area; as an equation p=F/A, where p is pressure, F is force and A is area; measured in pascals(Pa)
- 20. simple machine that looks like an inclined plank, but is forced into a object
- 21. device that helps us do work
