A gusset is a device, often triangular, used to reinforce a connection between two components. Gussets are commonly used in engineering, sewing and armour.

[edit] Sewing

In sewing, a gusset is a triangular or square piece of fabric inserted into a seam to add breadth or reduce stress. Gussets were used at the shoulders, underarms, and hems of traditional shirts and chemises made of rectangular lengths of linen to shape the garments to the body.[1]

Gussets are used in manufacturing of modern tights or pantyhose to add breadth at the crotch seam; these gussets are often made of breathable fabrics for hygiene.

[edit] Armor

Gusset is also an alternate spelling of gousset, a component of late Medieval armor.

the term "don't bust a gusset" comes from this sewing term. usually a piece of fabric sewn between two others to make up the difference to increase mobility or increase the size of your pant waist; the latter being more common in the early 1900s

[edit] Engineering

In civil engineering, gusset plates are frequently used to connect any number of beams or truss members to load-bearing columns. The members can be bolted, riveted or welded to the gusset plate. Their function is critical to the integrity of the structure they are supporting.[1]

In 1988, a failure in a gusset plate resulted in the collapse of a 300-foot radio telescope antenna belonging to the National Radio Astronomy Observatory.[2] Similarly, the National Transportation Safety Board (NTSB) indicated that rupture of the gusset plates of the I-35W Mississippi River bridge in Minneapolis, Minnesota, was the probable cause initiating the bridge's collapse.
