There the maple answer uses RootOf, I'm guess that because you have another issue in the expression. For instance A.s*Fy have units of Newtons, but the other part not. Best regards. Alvaro.

Left side of equation is N (kg*m/s^2), right side is J (kg*m^2/s^2). A dimension should be extra or missing in that equation. Probably not correct solution but if you equate units; Regards

RootOf expands easily [Example 1] 2. root is undocumented, most precious for dual solver [Example 2] 3. allvalues ... most precious in invlaplace [Example 3] Maple RootOf Example.sm (39kb) downloaded 23 time(s).
