A gusset is a device, often triangular, used to reinforce a connection between two components. Gussets are commonly used in
engineering, sewingand armour.
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 linento shape the garments to the body. [Burnham, Dorothy, "Cut My Cote", Royal Ontario Museum, 1973.]
Gussets are used in manufacturing of modern tights or
pantyhoseto add breadth at the crotch seam; these gussets are often made of breathable fabrics for hygiene.
Gusset is also an alternate spelling of
gousset, a component of late Medievalarmor.
Gusset plates are frequently used to fuse any number of load-bearing
columns with beams or trussmembers together. The members can be bolted, riveted or welded to the gusset plate.
A failure in a gusset plate resulted in the collapse of the 300 foot NRAO antenna. [cite web |url=http://www.gb.nrao.edu/fgdocs/300ft/300ft.html |title=300Foot Telescope Collapse |publisher=NRAO] Similarly, the
National Transportation Safety Board(NTSB) indicated that rupture of the gusset plates of the I-35W Mississippi River bridgein Minneapolis, Minnesota, may have been the initiating factor in the bridge's collapse.
