3D statics - Symbolic vector/tensor solving

Hello. 

 

I'm fairly new to Mathcad, but i hope someone can assist me with this:

I'm trying to solve some 3D statics, or make a template for it. At first i'm building 6 equations with 6 unknowns, I then want to solve this for each variable and afterwards put in the values. I've done it this way around in Maple, but i like Mathcad, and the price 😉

 

I have attached my crude attempt just to give a better understanding of what i am trying to do.

 Hope someone can help me or point me in the right direction.

B/R

The approach is generally OK. Especially the fact that you're intending to solve symbolically first.

Here's the same set in Mathcad 11:

Success!

You try to solve a linear system in six variables but the equations are not independent.

At least the  last three equations (its a system for  F1x,F1y and F1z) are not:

You are right, i jumped the gun on the variables, so I'm missing some stuff. I will give it another go and return.

Show please the picture of the problem!
