# Solution to Problem 625 | Moment Diagram by Parts

Mohd Naseem Hashmi

The distance between the centroid of the second triangle i.e. the centroid of the area of the moment due to the load 500 N about $R_1$ and the support $R_2$ seems to be wrong.
Actually, it must be $4-\frac{2}{3}=\frac{10}{3}$.
So the answer would be 5750 $N\cdot m^3$ not $7750\, N\cdot m^3$.
