The term "girder" in literature is often employed as a metaphor or technical descriptor to evoke the image of strength and structural support while also hinting at complexity beneath an apparently robust exterior. For instance, in one passage the keel is depicted not as a single, unyielding vertical girder but rather as a series of connected sections, suggesting that even what appears solid may be composed of interdependent, flexible links [1]. This nuanced usage encourages readers to consider how components, though individually distinct, work collectively to provide reinforcement, thereby enriching the metaphorical significance of "girder" in literary contexts.
