Hi all,

I have the following six equations:

1. Reaction-Y1 + Force13*sin(A1) + Force12*sin(A3) = 0
2. Reaction-X1 + Force13*cos(A1) + Force12*cos(A3) = 0
3. Reaction-Y2 + Force21*sin(A1) + Force23*sin(A2) = 0
4. Reaction-X2 + Force21*cos(A1) + Force23*cos(A2) = 0
5. Reaction-Y3 + Force31*sin(A2) + Force32*sin(A3) = 0
6. Reaction-X3 + Force31*cos(A2) + Force32*cos(A3) = 0

I have calculated the Reaction values for all 6 of them, and all the angles of each of them.

How would I substitute these equations into a Matrix, so that I can solve for the forces, using the form of

AX = B

Where A is a square matrix, X is a vector of unknowns (Forces) and B is a vector of knowns, i.e, the Reactions forces.

Any help will be appreciated. Thanks.

Damien
