← HistoryWhich consequence results when rope fibres degrade within a Viking-era rope bridge?
A)Shear strength experiences major dropoff✓
B)Torsional stress tolerance multiplies rapidly
C)Resonance frequency demonstrates limited change
D)Elastic modulus shows a massive expansion
💡 Explanation
Decreased fiber integrity causes reduced shear strength via intermolecular debonding, because weakened fibers can no longer resist shear forces effectively. Therefore, the bridge degrades catastrophically, rather than exhibiting increased torsional tolerance or modified material properties.
