Question

Problem with solve block

I am having trouble with the solve block on the attached worksheet.  It is using the maximize function within a solve block.  Please help me figure out what I am doing wrong.  The answer should be around 104 kip.  Adjusting the guess value does not help.  Thanks in advance for any help.

Looking at the behaviour of your sigma function, I'd have been tempted to use root to find the value rather than the solve block.

Or you could use the solve block with the fully self-contained version of sigma ... it gives the solve block less variables to play around with in its attempt to maximize the value of F ...
