Question
History

Which structural problem developed historically in timber ship construction due to alternating wet and dry conditions?

A)Rotting caused significant ballast shift
B)Hogging where keels bend upwards
C)Racking where frames slipped apart
D)Shearing from differential plank expansion

💡 Explanation

When wood repeatedly wets then dries, it encourages fungal growth, leading to wood rot which affects structural integrity, causing increased volume loss, leading to ballast shifting. Therefore rotting results, where hogging, racking and shearing would require imbalances within structural loading.
