Physics and Meccanica Razionale: vector calculus; equilibrium equation both for static and dynamic problems.
Geometry: vector spaces and linear operations; matrices and linear operators; linear systems; algebraic curves: conic curves.
Teaching methods Face-to-face both theoretical and practical classes.
Other information Attendance to classes: optional but strongly advised.
Learning verification modality Written test and oral exam.
Extended program Strain analysis. Stress analysis. Principle of virtual works. Elastic bodies and energy related theorems. Elastic Beams. Energy based methods for systems of beams.
Statically indeterminate structures and their solution. Barré de Saint Venant problem: axial force, bending moment, eccentric axial force, shear force and bending moment, torsion.
Plasticity and strength criteria. Strength of materials. Safety assessment.
Stability of the elastic equilibrium: buckling loads, Euler buckling.
