Which structural deformation results when a timber-framed medieval cathedral experiences differential foundation settlement?

💡 Explanation

When differential settlement occurs, the frame distorts because the foundations move unevenly, causing stress concentrations within the masonry walls, and tensile forces exceed mortar strength. Therefore, wall cracking results, rather than arch buckling, roof sagging or column shear which require compressive overload or material defects.
