Question

Why is the wall of a dam broad at its bottom?​

Answer 1

Answer:

Why is the wall of a dam broad at its bottom?

Explanation:

The reason is that the pressure exerted by a liquid increases with its depth. Thus, as the depth increases, more and more pressure is exerted by water on the wall of the dam. A thicker wall is required to withstand greater pressure, therefore, the thickness of the dam increases towards the bottom.

Answer 2

Explanation:

Wall of a dam is broad at its bottom because the water increases with depth. Hence, as we go towards the bottom of the water source, the pressure increases. To withstand this large pressure the walls of the dam are made thicker than at the top.
