Question

The wall at base of a damis made wider.why?

Answer 1

Answer:

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 walls increases towards the bottom.

Answer 2

Answer:

• The Dam is built wider at the base due to 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 walls increases towards the bottom
