All,
I am trying to set up a Mathcad Spreadsheet for precast header design. I am currently checking my angle moment capacity and LTB. While doing so I am trying to find r(sub Z) which takes the square root(Iz/AL). For some reason this equation is spitting out a matrix. Then when I go to input rZ into my Me equation I am getting an error. Any help or input would be appreciated.
See attached spreadsheet.
