- Homework Statement
- Is it possible to find Tensional force from Lagrange?

- Relevant Equations
- L=T-U

Lagrangian principle is easier to solve any kind of problem. But we always "forget" (not really. But we don't take it into account directly.) of Tension in a system when looking at Lagrangian. But some questions say to find Tension. Since we can get the equation of motion from Newton's 2nd law (where lots of force are taken into account, with too messy equation). Then can we get only tension force from the equation of motion without looking at Newton's 2nd law.
