1. Review
   • Global shape functions with Galerkin
     Deflection, X ⁴, X ², exact is (X ⁴ - 2 X ³ + X), comparison
     Thermal quadratic (exact), sine, comparison
   
   
   • Linear shape functions piecewise with several elements
     Axial deflection Axial 1,
     Statically indeterminant,
     combine thermal and mechanical stress
