Which outcome occurs when unsupported sections of Gothic cathedral stained-glass windows deform outwards under wind load?

A)Accelerated lead came corrosion
B)Increased compressive arch stress
C)Localized glass cracking failure
D)Weakened structural flying buttresses

💡 Explanation

When unsupported sections of stained glass deform, tensile stress concentration occurs because the glass's elastic limit is exceeded, leading to cracking. Therefore localized glass cracking results, rather than corrosion, compressive stress, or buttress failure, which are linked to different environmental and structural factors.
