The word "clevis" is pronounced as /ˈklɛvɪs/ in the International Phonetic Alphabet. This word is mainly used in mechanical engineering and refers to a U-shaped metal fastener with holes at the ends. The pronunciation of this word is derived from its etymology, which is the Middle English word "cles", meaning key or a fastener. The spelling of "clevis" is consistent with English spelling conventions, where the letter "s" is used to indicate a plural form or an ending sound. It's important to spell this word correctly to avoid confusion in mechanical applications.
A clevis is a type of fastener or coupling device that is widely used in various mechanical applications to connect two parts or objects together. It is composed of two main components: a U-shaped metal bracket called the clevis body and a metal pin or bolt known as the clevis pin.
The clevis body typically consists of two parallel arms with a hole or slot at the ends to accommodate the clevis pin. The arms are fastened or welded to one object, while the clevis pin is inserted through the holes in the clevis body and the other object to be joined. The clevis pin may have a hole at one end to allow for the insertion of a cotter pin or a retaining clip, ensuring that the pin remains securely in place.
Clevises are commonly used in mechanical systems to provide a strong, yet adjustable connection between different components like rods, levers, or cables. They allow for easy installation and removal of parts, facilitating repairs and adjustments. Clevises can also be found in various industries such as automotive, aviation, construction, and agriculture, where they are used in applications such as hydraulic cylinders, suspension systems, linkages, and control mechanisms.
Overall, the clevis is an important component that enables the safe and efficient assembly of mechanical systems, providing a versatile and reliable connection between two parts or objects.
The word "clevis" originated from the Old French term "clivet", which was derived from the Latin word "clavis" meaning "key". The shape of the clevis, resembling the keyhole of a lock, led to the association with the Latin word. Over time, the spelling and pronunciation evolved, ultimately becoming "clevis" in English.
