Point of application of generalized forces of constraint

Click For Summary
SUMMARY

In Lagrangian Dynamics, generalized forces of constraint are applied at the location of the corresponding generalized coordinate, although this application may not be explicitly detailed in standard texts. Generalized coordinates represent a configuration of the system rather than a specific point in space, indicating that the concept of applying a force "at" a generalized coordinate may lack physical meaning. This distinction is crucial for understanding the implications of constraints in dynamic systems.

PREREQUISITES

In Lagrangian Dynamics, I assume that generalized forces of constraint are applied at the location of the corresponding generalized coordinate. I don't recall seeing anything explicit about the point of application in the text.

Not necessarily. The generalized coordinates represent a configuration of the system, not a point in space. So there may not be any sense in which a force can be applied "at" a generalized coordinate.
