The term "rowlock arch" is pronounced as /ˈrɒlək ɑːtʃ/ and describes the structure that holds an oar in place on a boat. The word "rowlock" refers to the small device that keeps the oar in place and the term "arch" refers to the curved structure that surrounds it. The spelling of "rowlock arch" is straightforward, with each word spelled as it sounds. The term is commonly used in the boating world and is essential for those interested in building or repairing boats.
A rowlock arch is a specific architectural element that can be found in the construction of bridges or other structures that require the support and distribution of weight in a specific manner. Also known as a bondstone or skew arch, a rowlock arch is designed to transfer the vertical loads across a span by following a curved or arched form.
Typically made out of stone or brick, a rowlock arch is constructed by using rowlocks, which are specially shaped masonry units placed in a row in the form of an arch. These rowlocks are key components that facilitate the strength, stability, and load-bearing capabilities of the arch. They are laid perpendicular to the arch's curve, forming a supportive structure that helps resist lateral and vertical forces.
The distinctive arch shape of a rowlock arch offers numerous advantages, such as increased stability, efficient load distribution, and aesthetic appeal. By distributing the weight along its curved path, the arch effectively minimizes stress on its individual components, promoting structural integrity and longevity.
Rowlock arches can be found in various architectural designs, including bridges, viaducts, aqueducts, and tunnels, where their unique construction allows for successful weight transfer and support across spans. Their implementation in construction has been prevalent for centuries, showcasing their efficiency and durability in sustaining a wide range of structures.
The etymology of the word "rowlock arch" can be traced back to the Middle English and Old English languages.
The term "rowlock" comes from the Middle English word "rolok", which means "a pivot point" or "a device used for rowing". It is composed of two elements: "roe", which is related to rowing or steering a boat, and "lok", which means "a fastening" or "a device with a hole through which something can pass".
The word "arch" has its origin in the Old English word "arc", meaning "a curved structure" or "a bow". It was derived from the Latin "arcus", which has the same meanings.
When these two words are combined, "rowlock arch" refers to a structure or a curved architectural element used in the construction of rowing bridges or platforms.
