To create sketches of structural elements and actions.
To know the fundamental elements of the deformable body (stresses, strains, displacements, constitutive laws, material constants, characteristic curves).
To know the fundamental hypotheses of Strength of Materials and the general methods of problem solving.
To establish the state of stress, strain and displacement in case of simple actions.
To formulate and understand (checking, design, bearing capacity) the strength conditions of structural elements in case of simple actions.
