Which consequence resulted when ancient Viking longships navigated icy waters?

💡 Explanation

Hull fracture occurs due to ice formation expanding into wood pores; this is a process of ice wedging. The expansion stresses the hull beyond its yield strength, because the water freezes, therefore the hull fails, rather than retaining its structural properties or changing frictional characteristics.

• In the late Roman Empire, which consequence resulted from improperly heat-treating iron pilum tips?
• Which outcome occurred when Incan stonework terracing exceeded frictional limits?
• Which structural failure mechanism most jeopardized undermining operations during Roman sieges of walled cities?
• Which outcome occurs when differential thermal expansion stresses Incan masonry?
• During Roman concrete construction, which outcome indicates insufficient pozzolan content?
• Which purpose did the raised beds found within pre-Columbian chinampas in Mesoamerica most effectively serve?
