"This value must be a vector" error in force analysis

[RM_9744827]

Hi everyone,

I am working on a force analysis for a kinematic mechanism. I have been able to resolve most of the errors that I'm seeing, except for a few. I have two declaring that the value must be a vector, and I'm not entirely sure how to correct this. I also have two errors saying my array index is invalid when I'm simply trying to label my variables. Any help here is greatly appreciated. The file is attached.

I have the impression that you made a big mess! You don't have to use vector elements but subscript variables. For example, θ₂ should be written θ point 2 and not θ control [ 2. The same for δ₄₄ and all the rest. You used the symbol of logical equality, but I believe that the assignment is necessary ie the colon :. You have defined the same functions several times (A (.), B (.), C (.) ...) You have to rewrite it correctly and you will see that it will work.
