## Main Question or Discussion Point

hi all ,

i am new at this forum , so i don't exactly know the rules about the topics and their sorting

i am self studying lagrange dynamics.

so my question is : when writing lagrange equations for aparticle ,& the particle

is in conformity with the constraints ; why the generalized forces

arenot containing the constraint forces ?

thanks in advance.
