So I have a system of equations (composed of force and moment eqns) and I can split them up into matrices which will then look like this:(adsbygoogle = window.adsbygoogle || []).push({});

Ax =B

I know the matricesAandBare correct, because when I plug in known values for x from a working prog, I get the correct values forB. So that must meanAandBare correct, right?

HOWEVER, I am not able to invertAso that I may solve x = inv(A) *B.

The determinant ofAis 0, so it's a singular matrix.

So what is the significance of an singular matrix?

Maybe there are redundant eqns involved? Am I looking at a statically indeterminant problem?

How does one fix this?
