Need advice for the search function (numerical solution of equation)

Hey,

i would need another short help of you guys.

I have an equation and need to solve it for a variable with the search(x) function. Now my problem is that i need to do it for many loadcases.

I have given vectors for the variables in the equation and a given vector for the beginning search variable.

How can i do it in mathcad so that mathcad is solving the equation for every row of the vectors.

I have an given example in the mathcad file.

I have problems here how to define the code 😞

Best thx

I tryed to add a for Code but not working hmmm

Maybe its only a small failure

You can't use find in a program.

You can use the symbolic solver to get a function.  Because you have a quadratic function there are two solutions.  You must decide which is physically relevant.

thx for the tipp.

The problem is i tryied this but what i dont understant:

the numerical solution gives a result of 6.819 mm what is the right result

But when i solve it analytical directly i always get - 6,819 . What is the wrong result and minus.

Why do i get a minus. Maybe im loosing a result by directly solving.

But i think the numerical solving by vectorising is the better method since i have much more complicated solutions.

Thx for the good tip. I really need it. I was close to the solution i had the arrow on the right side of the equation upper the search function.
