Which outcome arises when ice accumulates excessively on a medieval timber bridge?

💡 Explanation

Excessive ice increases the dead load on the bridge, meaning gravitational force. This increases shear stress via static loading; therefore, the shear strength limit is potentially exceeded, leading to structural failure rather than timber rotting, material fatigue, or tensile strength reducing.
