Pronunciation: [tˈɒɡə͡l d͡ʒˈɔ͡ɪnt] (IPA) 
The word "toggle joint" is spelled with a "t" followed by "o"g and "g" again, then "l" and "e". The IPA phonetic transcription for this word is /ˈtɒɡəl dʒɔɪnt/. The "o" is pronounced as the vowel sound in "hot" and the stress is on the second syllable. A toggle joint is a mechanical joint that is made up of two arms connected by a pivot point or toggle, which enables them to move together in a specific way.
A toggle joint refers to a mechanical linkage or mechanism consisting of two arms connected by a pivot joint or hinge at one end, with the other ends connected to a fixed point or object. This type of joint allows the connected arms to pivot in a particular way, where one arm moves in an arc while the other arm follows a straight path.
The toggle joint is primarily designed to provide a force-amplifying effect or create a significant mechanical advantage. By applying force to one of the arms, the joint can establish a large output force on the other arm. This mechanical advantage is particularly useful in various applications, such as machinery, engineering, and construction, where a high force is required to accomplish tasks efficiently.
Toggle joints have been used in different devices like presses, breakers, stone crushers, and mechanical squeezing devices. The joint’s ability to convert a small input force into a larger force output makes it an effective mechanism for different industrial uses.
Overall, a toggle joint is a type of linkage or mechanism commonly used to multiply force or create mechanical advantage by allowing one arm to pivot while the other arm moves in an arc. Its presence in various machines and systems illustrates its practical importance and effectiveness in amplifying force and achieving mechanical advantage.
An elbow or knee joint consisting of two bars so connected that may be brought into a straight line.
Etymological and pronouncing dictionary of the English language. By Stormonth, James, Phelp, P. H. Published 1874.
The word "toggle" comes from the Middle English word "togele", which means a wooden peg. It goes back to the Old English word "tang", meaning a tongue or projection, and originates from the Proto-Germanic word "*tangō". The term "joint" in this context refers to a mechanical connection or articulation between two components. Therefore, the etymology of "toggle joint" can be traced back to the Old English word for a wooden peg or tongue and the concept of a mechanical connection.
