Which beam is more likely to break?

Could you please clarify which beam you are referring to? Are we discussing two specific beams, and if so, what are the characteristics of each? For instance, are they made of the same material? Are they subjected to the same or different loads? Do they have any visible signs of wear or damage? Understanding these details is crucial to determining which beam is more susceptible to breaking. Could you provide more context or specific information about the beams you're comparing? This would greatly assist in formulating an accurate answer.
