- How to calculate reaction forces at multiple points.

Thanks in advance to anyone that can help me solve this problem, its causing me a real headache.

I need to transport a rather large frame that supports a large heavy item. The weight is not evenly distributed along its length. I know the various distances between the supports, the total weight and the center of mass.

I know how to calculate a simple 2 support situation.

Where Wr is weight at rear, Cg is distance from front support to Center of mass and D is distance between the 2 supports. Wf is weight at front.

Wr = (WxCg)/D

Wf = W-Wr

BUT... how do I go about calculating the reaction force (weight on each point) for the problem outlined below??
