Which structural problem emerges when a cantilever bridge experiences excessive asymmetrical loading?

💡 Explanation

When asymmetrical loading occurs on a cantilever bridge, torsional instability develops because the unbalanced forces create a twisting moment around the bridge's longitudinal axis. Therefore, torsional instability is the primary risk, rather than shear buckling, fatigue cracking, or resonance, which stem from different loading conditions.
