syllabus and bibliography 1. Covariant formulation of restricted relativity: Newton and Maxwell laws and the principle of relativity; Einstein’s postulates; three-dimensional space covariant formulation; tensors in Minkowski space; conservation of the linear momentum tetravector; total inelastic collision; particle with null mass; centre-of-mass system; collision of two particles; some tetravectors in Physics. 2. Small oscillations of many-particle systems: single degree-of-freedom system; multiple degree-of-freedom systems; the double plane pendulum; vibrations of a linear triatomic molecule. 3. Elasticity theory: second order tensor and orthogonal transformations. 3.1- Deformations tensor: unidimensional and three-dimensional deformations, the deformation tensor; incompatibility relations. 3.2- Tension tensor: tension force per unit volume; balance conditions. 3.3- Hooke’s law: work done by tension forces; elastic bodies; Young’s modulus and Poisson’s ration; the tension graphic versus deformation; theory of rupture and tensile strength. 3.4- Applications to elastic and isotropic materials: traction of a bar; tension in a hollow cylindrical tube; torsion of a bar; flexion of a beam. 3.5- Wave propagation in an infinite and homogeneous medium: flow speed; motion equation; linear approximation for solids; wave propagation in infinite isotropic media: waves and P-waves. 4. Constitutive equations for fluids: fluids in balance, Euler equation; fluids with viscosity; Navier-Stokes equation. Bibliography of reference BHATIA A. B.; & SINGH, R. N. (1986).
