Hi. It seems that you put kd( ... ) instead kd*( ... ) in the maple solver.

Best regards.
Alvaro.

Alvaro thanks for you answer but

"kd" is the only value unknown

In the first expression it is kd( ... ). In the second it is kd*( ... ). 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.

Alvaro is right.
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

1. RootOf expands easily [Example 1]
2. root is undocumented, most precious for dual solver [Example 2]
3. allvalues ... most precious in invlaplace [Example 3]
