Lagrangian Mechanics: Solving Eqtn 2.28, 2.36, and 2.37

Click For Summary
SUMMARY

The discussion focuses on solving equations 2.28, 2.36, and 2.37 from Lagrangian mechanics. Participants emphasize the importance of understanding the force notation, specifically the term F_i = \vec{F}, to derive the necessary relationships. Clarification on the meaning of the index 'i' is also highlighted as crucial for solving the equations. The conversation indicates a need for deeper comprehension of these concepts to tackle the posed questions effectively.

PREREQUISITES
  • Understanding of Lagrangian mechanics principles

I don't know how to do the 4 questions.
And I only have some ideas on questions 1.
The details are written on the photos.

Thanks for help.

Eqtn 2.28 2.36 2.37 are given on the photo.

you need to realize that [tex]F_i = \vec{F}[/tex] then you can derive your relations

either that or what is the meaning of the i index
