| | Portuguese translation:extensão de alavanca | Explanation:
alavancas e extensões de alavanca
http://en.wikipedia.org/wiki/Cheater_bar
Cheater bars are usually used to free screws, bolts, and other fasteners that are difficult to remove with a ratchet or wrench alone. Cheater bars are also commonly used to operate valves.
When the handle of a wrench or ratchet is inserted into a cheater bar, the additional distance makes it possible to generate the required torque with the same amount of force being applied. However, the work done is the same with or without the cheater bar because the torque and angle of rotation needed to accomplish a particular task does not change.
A cheater bar is sometimes called a pipe extension or an extension pipe. |
