![]() ![]() We know the vertical and horizontal coordinates of this centroid, but since the equivalent point force’s line of action is vertical and we can slide a force along its line of action, the vertical coordinate of the centroid not important in this context. Modify or delete previously entered loads as necessary. For a rectangular loading, the centroid is in the center. The load type may be a distributed load or in-span concentrated loads. ![]() The line of action of the equivalent force acts through the centroid of area under the load intensity curve. To use a distributed load in an equilibrium problem, you must know the equivalent magnitude to sum the forces, and also know the position or line of action to sum the moments.
