Please suggest a good book on Mechanics covering the following topics-

Newtonian Mechanics – difficulties to handle coupled equations, Constraints (both time dependent and time independent), Degrees of freedom, Generalised co-ordinates, Generalized force, potential and kinetic energy, Lagrange’s equation of motion and Lagrangian, Ignorable co-ordinates, Hamilton’s equation and Hamiltonian.

Also suggest books on Field theory and Vibration & Waves.The syllabus is as follows-
