What is the term for the plywood panel added to strengthen the intersecting members of a crate?

The term for the plywood panel added to strengthen the intersecting members of a crate is known as a gusset. Gussets are used in the construction of crates to provide additional support and stability at joints where different structural members meet. By reinforcing these intersections, gussets enhance the overall integrity of the crate, helping to distribute weight evenly and prevent structural failure. This is especially important in packaging and shipping, where the crate may be subjected to various stresses and loads.

The other options refer to different structural elements. A bracket is typically a support that holds two parts together, but it does not serve the same function as a gusset. A strut is a structural component that resists compressive forces, while a beam is a long, sturdy piece that supports loads across a span. While all these components are important in construction, they serve different purposes compared to a gusset, which is specifically designed to strengthen and stabilize intersecting members in a way that enhances the overall stability of the crate.
