← HistoryWhich risk increases when historical Viking rope bridges experienced freezing rain?
A)Increased shear stress on supports✓
B)Reduced catenary curvature stability
C)Elevated tensile strength properties
D)Decreased modulus bending stiffness
💡 Explanation
Increased shear stress occurs because ice accumulation magnifies the load on the ropes and anchor points, enacting a form of static MECHANISM which disproportionally burdens those elements. Therefore shear stress increases, rather than tensile capacity or stiffness decline normally.
