grandnat_6: Are you sure you gave me accurate values for xG and yG? Could you double-check the accuracy of those two values? Point G defines the location and slope of both beams, and I'm wondering if it might be throwing a few of my numbers off. Also, what is the x dimension from E to the bucket tip (where the applied loads are applied)?

Regarding your questions in post 38, the plus (+) sign means, it is a moment summation at an infinitesimal distance to the right of the specified x coordinate. Regarding your second question, moments are computed from the centerline of beam 1, until we get to beam 2. Then moments are computed from the centerline of beam 2. The vertical distance from point B to FEx is 19.258. The vertical distance from point B to FDx is (19.258 - 3.1980).
