During a Roman siege, which risk increases when a wooden siege tower's supporting beams experience prolonged exposure to targeted fire?

💡 Explanation

Prolonged heat exposure causes creep, a type of bearing failure, because the elevated temperate reduces a structure's resistance to deformation under continuous compressive load; therefore, the tower collapses due to excessive deformation rather than sudden fracturing or vibrations.
