Problem with programming in Mathcad Prime 2.0

[ptc-4735426]

Hello,

I'm having trouble programming a while loop for to determine the optimal height in a beam deflection problem for school. I keep getting the error, "These units are not compatible," but if I remove all of the units I get the error, "This expression is divided by zero. It cannot be computed."

Attached is the program I am working with.

Thanks

You have h as Stefan–Boltzmann const:

If I change h to ht the same error message still appears.

You welcome!

Tha variable h must have a correct value before start the loop.

Chek it please!

If I give h a value then it won't loop. The program just computes the one value of h.

Thanks for all your help!

I think You give not correct value.

Hi Alex,

I think that you may have a problem with the logic of the while condition.

For the i=1 initial condition, the first condition is true, but the second is not and therefore the while loop does not execute.

Hope this helps
