History

Sustained hogging deformation afflicted wooden ships despite frame reinforcement; which mechanism led to compromised hull integrity?

A)Differential swelling of planks
B)Rivet fatigue from wave stress
C)Brittle fracture from ice collisions
D)Electrolytic corrosion of fastenings

💡 Explanation

Differential swelling causes hull distortion because wood expands unevenly with moisture content; therefore, sustained bending stresses occur, rather than uniform distribution. These exceed material yield strength and plastic deformation arises contributing to hogging failure.
