In analyzing structural stability, the center of gravity and load distribution are crucial factors. The center of gravity represents the point where the weight of the structure is evenly distributed. If a structure's center of gravity is too high or not aligned with its base, it can lead to tipping or instability, especially under dynamic loads such as wind or seismic activity.

Load distribution refers to how forces are spread across different parts of the structure. Proper load distribution ensures that the structure can withstand both static and dynamic loads without experiencing excessive stress that could lead to failure. Understanding how loads are applied and transmitted through the structure allows engineers to design elements that resist those forces effectively, maintaining overall stability.

While the total weight of the structure is important since heavier structures may require more robust support systems, it is not the only determinant of stability. The type of materials used can affect strength and flexibility but does not alone ensure stability without proper analysis of load distribution. Environmental conditions, such as wind and seismic activity, also play a role but must be evaluated in conjunction with load distribution and the center of gravity to assess the stability comprehensively.
