The students will be able to:
CO1: understand the basic concepts of coordinate systems and degrees of freedom and apply on various problems. CO2: learn about Hamilton's and Lagrange's Equations using calculus of variation and apply them to solve problems of mechanics. CO3: gain Knowledge about Conservation principles, Noether's theorem, Eulerian angles and Euler’s theorem and apply these concepts to relevant problems. CO4: understand basic Lagrange's- Poisson’s brackets and Canonical transformation then analyze their relations. CO5: learn about the Action angle variables, Lagrangian formulation and their applications. |
