Calculate the eccentricity of a trapezoidal dam with a distance between the centre of gravity and point where the resultant cuts the base is 5m. The bottom width of the dam is 3m.

Calculate the eccentricity of a trapezoidal dam with a distance between the centre of gravity and point where the resultant cuts the base is 5m. The bottom width of the dam is 3m. Correct Answer 3.5m

The eccentricity (e) = Z – b/2. Z= distance between the centre of gravity and point where the resultant cuts the base is 5m. = 5-3/2 = 1.5m.
