Goals

Provide basic notions required for the mechanical design of rotating machines for energy production.

1- Introduction to the theory of vibrations:
Introduce Lagrange equations and solve the equations of motion in simple cases and for small oscillations around equilibrium

2- Linear elasticity of solid bodies:
Understand concepts of stress and strain
Introduce linear elastic consitutive law
Understand the concept of elastic criterion
Structural design using a finite-element method program
