Which structural problem famously plagued initial riveted construction of iron ships during the 19th century?

💡 Explanation

When iron plates were joined via iron rivets in early ships, seawater acted as an electrolyte, causing galvanic corrosion because iron rivet composition differed from the iron hull. Therefore galvanic corrosion occurred, rather than brittle fracture, hogging, or weld cracking, as historical riveting construction methods preclude those factors.
