- 16.1: Introduction
- Lagrangian and Hamiltonian mechanics have been used to determine the equations of motion for discrete systems having a finite number of discrete variables \(q_i\) where \(1 \leq i \leq n\). There are important classes of systems where it is more convenient to treat the system as being continuous. Fluid and gas dynamics, as well as electromagnetic fields, are other important classes of continuous systems.

- 16.3: The Lagrangian density formulation for continuous systems
- The Lagrangian density formulation for continuous systems in both one and three spatial dimensions.

- 16.5: Linear Elastic Solids
