Which mechanism caused repeated cracking in the Liberty Bell after its arrival in Philadelphia?

💡 Explanation

When the Liberty Bell was rung, stress concentration occurred at the sharp corner of a pre-existing casting flaw because the bell material lacked sufficient tensile strength, leading to crack propagation. Therefore cracking resulted, rather than expansion, corrosion or embrittlement which require different environmental or material conditions.
