Which joint design is considered the strongest for minimizing failure in boomilever structures?

The overlap with glue joint design is considered the strongest for minimizing failure in boomilever structures because it maximizes the surface area available for bonding between two components. This increased surface area provides a more secure and robust connection, allowing for the distribution of forces across a larger area, which can help to prevent localized stress concentrations that could lead to failure.

In addition, the adhesive used in this joint type adds additional strength by binding the materials together at a molecular level, creating a more unified structural component. This type of joint is especially effective in tension and shear forces, which are commonly encountered in boomilever structures during load application.

Other joint types, while they each may have specific applications, typically do not provide the same level of strength and reliability under varying load conditions as the overlap with glue design. For example, butt joints without adhesive can be quite weak, as they rely solely on the mechanical fit of the parts, making them susceptible to failure under tension or shear loads. Lap joints might offer some strength but usually don't match the strength integrity provided by the overlap with adhesive. Simple connections typically lack the reinforcement needed to withstand significant loads, making them prone to failure in more demanding applications.
