← HistoryWhich consequence results when a rope bridge experiences an increased load at a central point, impacting medieval trade routes?
A)Increased shear stress at anchorages✓
B)Reduced catenary curvature uniformity
C)Decreased aerodynamic bridge stability
D)Augmented bridge tensile capacity
💡 Explanation
Increased load generates higher shear stress because tension distributes unevenly across rope strands acting as structural supports, therefore the rope anchorages are more liable to failure, rather than the integrity of each strand under uniform load conditions.
