Across
- 1. The result of effort being put into a machine
- 6. Famous stone structure in England that was the first to be built using a compound pulley system
- 9. In a gear train, motion is transmitted to this gear
- 10. A small gear driving a large gear will do this to torque.
- 12. Lever with the load and effort on opposite ends and fulcrum in the middle.
- 14. Gears with winding teeth that provide better meshing and less noise.
- 16. A gear within a gear train that creates space between two outside gears and cause them to rotate in the same direction.
- 17. A small gear driving a large gear will do this to the speed.
- 18. Tool used to apply a specific measure of torque to a nut or bolt.
- 19. Good example of a 2nd class lever
- 20. Another name for Load.
- 22. A mechanism consisting of a wheel with a groove in its rim used to change the direction and magnitude of a force exerted by a rope or cable.
- 27. Two gears together will cause this change.
- 28. Pulley mechanism that uses fixed and movable pulleys in combination
- 29. The wheel and axle first appeared as this wheel.
- 30. Name given to two gears attached to the same shaft
- 32. These gears rotate opposite each other
- 33. Type of gears used to change the direction of motion.
- 35. A comparison in mathematical terms between two or more gears in a gear train.
- 37. A twisting force around a set point that causes rotation.
- 40. The effort put into a machine
- 41. Motion swinging back and forth in a circular arc.
- 44. In a gear train, this gear causes motion to the other gears
- 46. Mechanism using irregular shaped components connected to a shaft used to transform rotary motion into linear motion
- 48. An enclosed casing containing various sized gears in operation.
- 50. A flat angled surface with no moving parts.
Down
- 2. A gear system consisting of one or more outer gears revolving around a central sun gear.
- 3. Leave with load and fulcrum opposite ends and effort in the middle
- 4. Functions as a moving inclined plane
- 5. The state of a lever when it is perfectly balanced.
- 7. Determined by comparing effort forces with load forces or effort distances with load distances.
- 8. Type of gear used in combination with a chain
- 11. Lever with fulcrum and effort on opposite ends and load in the middle
- 13. A pulley system is used to operate this.
- 15. A series of gears that transmit rotary motion and torque by means of interlocking teeth.
- 21. Good example of a 3rd class lever
- 23. Type of pulley that does not increase the amount of force applied
- 24. Motion back and forth in a straight line
- 25. Gear train that converts rotary motion into linear motion.
- 26. The point on which a lever rests or is supported and on which it pivots.
- 31. The unit of force used in countries that use metric measurements instead of pounds.
- 34. A beam used to lift or move a load located at one point by exerting effort force at a second point while turning on a fulcrum located at a third point.
- 36. Circular motion that takes place when an object spins on an axis
- 38. The degree to which work is accomplished with the smallest amount of wasted effort and expense.
- 39. Type of mechanical advantage determine by comparing forces
- 42. Straight-cut gears that are the simplest and most common type of gear.
- 43. Gear train motion that creates a continuous straight-line motion.
- 45. Type of mechanical advantage determined by comparing distances
- 47. Mechanism with various shaped parts linked together in such a way as to create a desired repetitive movement.
- 49. Place where wheel and axle were first used for transport.
