But the remainder of what you show does NOT involve symbolic evaluations/calculations. </P><P>So T.max_2_10k is just calculated based upon what the numeric calculator has and knows, which includes T.max_2_10k_relief = 1 lbf.</P><P>The only part where T.max_2_10k depends on T.max_2_10k_relief is in the final root. Is it possible that sigma * y squared is much much larger than 3 * T.max_2_10k_relief squared, and therefor you (seem to) see no influence of T.max_2_10k_relief on T.max_2_10k?</P><P></P><P>Luc</P></BODY></HTML> Tue, 23 Feb 2016 09:30:53 GMT https://www.ptcusercommunity.com/t5/Mathcad/Algebraic-equation-solver-for-unknown-variable/m-p/71605#M28142 LucMeekes 2016-02-23T09:30:53Z
