Undetermined Multipliers

#Physics
Another way to use an equation of holonomic constraint to reduce the degrees of freedom of a system rather than simply performing a substitution using the equation of constraint. Is used to find the forces of constraint

Notes

• Requires constraints to be expressed in terms of generalized velocities
• E.g.: $\displaystyle \sum_{i}A_{i} \dot{x_{i}}+B=0,, i=1,2,3$
