← HistoryWhich consequence would result if Viking rope bridge construction lacked sufficient fiber twist?
A)Increased susceptibility to weathering effects
B)Catastrophic tensile failure under load✓
C)Reduced deck planking interlocking strength
D)Accelerated fatigue crack propagation rate
💡 Explanation
Cable tensile strength directly relies on fiber twist to create FRICTIONAL ADHESION; because ropes transfer load amongst fibers via friction, fibers slipping causes catastrophic tensile failure, therefore bridges lacking fiber twist risk immediate collapse, rather than merely weathering or fatigue.
