Single support problems
S = w1 + w2 + w0 (w0 = weight of the rule)
w1d1 = w2d2 because the forces must be balances to support the object
2 support problems
If COM is midway between supports the support force is half the weight of the object on each beam
If its not midway take moments about where both supports are in contact with the beam (e.g)
About X - Sy = Wdx/D
About Y - Sx = Wdy/D
Sy and Sx are the 2 pont where the weight is supported
W is the weight of the object overall
dx and dy are the distances from the support to the centre of mass
D is how far the 2 supports are apart
