← HistoryWhich consequence arises from excessive hysteresis in early hemp cordage used on Viking longships?
A)Sails lose their aerodynamic shape✓
B)Increased propensity for rope breakage
C)Substantial reduction in ship speed
D)Inability to effectively furl sails
💡 Explanation
Excessive hysteresis causes sail deformation because the Cyclic stress causes rope fibers to irreversibly stretch affecting sail shape rather than elastic return. Therefore, Viking longships experienced reduced sail performance rather than immediate rope breakage and speed loss.
