The Shape of Seashells

SEASHELLS enable mollusks to live in harsh conditions, resisting tremendous pressures on the seabed.
This ability to provide optimum protection inspired engineers to study the shape and structure of seashells with a view to designing vehicles and buildings that will protect their occupants.
In the case of the bivalve, it was found that the ribbing on the exterior of a shell directed stresses toward its hinge and outer edges.
In contrast, the curving exterior of a spiral shell directed pressure toward its core and wide top.
