Generalized
2D/3D• Generalized[cnum] returns the list of generalized forces, or Lagrange multipliers ( 1, 2, ... ) associated with constraint cnum in the current model.
• The cnum argument can take any of the forms accepted by Constraints to obtain velocity terms from multiple constraints.
• Generalized is also an element of the MakeRules option setting.
• MakeRules->{... , Generalized, ... } causes the generalized forces to be included in the interpolated rules returned. • Generalized[All] returns the entire vector of Lagrange multipliers.
• The generalized force vector contains one Lagrange multiplier, n, for each constraint equation in the current system.
• Transpose[Jacobian[cnum, All]].Generalized[cnum]  Loads[All] returns the entire static force balance equation associated with constraint cnum.
• The value of the Lagrange multipliers cannot be directly interpreted as a force or moment without some understanding of the explicit form of the mechanism equations. Use the Reaction function to convert generalized loads into the reaction forces at each constraint.
• See also: Centrifugal. Further Examples Load the Modeler2D package and define a simple model. Here are the generalized forces associated with the Translate2 constraint.
