Differents units in the vector of results

When you resolve a system with variables that have associated the units of measure and where the vector of the results contains different kind of units, you may have problem, not to resolve the problem, but into the view and extrapolation of the results.

I have resolve this issue in this manner.

Yes, thats the standard workaround and you can omit the symbolic evaluation if you provide guess values for F2 and M2. This is especially important in cases where the symbolics is not able to find a solution (which happens very often in real life problems).

And yes, you are right - Prime is able to display matrices with elements of different dimensions. One of the very few advantages of Prime.

Yes. In fact if the problem solving is difficult because of a large number of variable, nonlinearity, it is better set the initial values of the unknowns, so you force the program to solve the problem numerically instead of symbolically.
