Which risk increased when siege towers became taller during Roman sieges?

💡 Explanation

When siege towers were built taller, the center of gravity shifted upwards, making them more prone to instability. This caused mechanism induced topple, because torque generated increases with offset, leading to tower collapsing easily. Therefore toppling is increased, rather than other factors, which required different specific conditions.
