I'm having a problem with MathCAD 15 to calculate forces.
I need 15 variabels (Fay Fax Faz, Fby Fbx Fbz, Fcy Fcx Fcz, Fdy Fdx Fdz, Fmmpy Fmmpx Fmmpz) and had 21 formulas. I red somewhere that it had to be 15 formulaes for 15 variables.
So i managed to get rid of 6 formulas.
Still undefined when i try to use the "find" function.
Hope someone can help.
when using the error tracing tool (Right-click on solution and choose "Trace Error") it says that your variable Rbdx (among others) is not defined. These need to be defined as starting values.
are missing some initial guesses
Thanks both for the very fast reaction!
I can't work on it right now, probably sunday.
I will check everything like you both said.
Still having a lot of problems with the answers.
For now, I Need:
F.mmpy = 190,2558 [N]
F.mmpx = 0 [N]
F.mmpz = 0 [N]
Can't share my current file in this text..
I've started all over again because I couldn't get it working correctly.
I hope someone can help me because my deadline is friday...
1. You have 12 equations and 8 unknowns!
2. Your system is linear. Use please the lsolve function! See please Given/Find and lsolve for one problem here 17.15 and 17.16 here Study 17. Cogeneration (CHP), trigeneration (CCHP) and quadrogeneration (CCHPI) or how much of m...
will it solve with singular value decomposition? (svd in Mathcad)
Even using svd2, you can not find the solution.
