| 21. | This offered steady mechanical advantage on any setting.
|
| 22. | The levers are about shoulder height since they must supply a mechanical advantage for the operator.
|
| 23. | The first Prusik knot provides the mechanical advantage.
|
| 24. | Introduced in the late 1800s, this invention combined the corkscrew and mechanical advantage in one device.
|
| 25. | Ideal mechanical advantage correlates directly with velocity ratio.
|
| 26. | A line with a mechanical advantage of 4 has a velocity ratio of 4 : 1.
|
| 27. | :1 ) This is gives ideal mechanical advantage.
|
| 28. | There is sometimes confusion about how much theoretical mechanical advantage is provided by the trucker's hitch.
|
| 29. | This setup gives Pat Robertson the maximum mechanical advantage at the last few inches of travel.
|
| 30. | If the mechanical advantage is less than ~ 1, then it's not really a functional mallet anymore.
