0 a second layer of cloth that is sewn into a piece of clothing to make it larger, stronger, or more comfortable:
The fourth object has a gusset or projection over itself.
The gussets made the bags easy to fill, but caused fractures in the foil layer that allowed cold air to enter over time.
Ribbed grosgrain may be used similarly to twill tape for internal gussets and reinforcements.
These calculations are made based upon the forces and loads applied to the gusset plate through the nearby steel components.
During the wreckage recovery, investigators discovered that gusset plates at eight different joint locations in the main center span were fractured.
Gusset plates are relatively flexible and minimize bending moments at the connections, thus allowing the truss members to carry primarily tension or compression.
Rather than merely a slightly-curved top plate with triangular gussets, it was now possible to roll a semi-circular plate.
Some bags have gussets to allow a higher volume of contents.
