Minimize: 6 variables and 4 equations

i have these 4 nice equations with 4 variables c.1 , c.2 ,c.3 ,c.4 im trying to set up a nice beam deflection algebra template. but i cant find any way to solve it, tryed with matrix and solve block no lock any ideas ? Smiley Happy.

Re: Minimize: 6 variables and 4 equations

Fortunately there are only 4 unknown variables to solve with the four equations. And one (c.2) is really simple.

Did you consider putting the 4 equations in a vector and solve for the 4 unknowns simultaneously, like:

You cannot use numerical methods like a solve block unless you have numerically defined all necessary variables (F.A, F.P, l.AP,...)
