Static analysis: constraint reactions and internal forces

After having assumed arbitrary values for geometrical dimensions and static actions for the models below, compute analytically:

The values of the constraint reactions;

The functions of axial force $($if present$),$ shear, and bending moment, and the relevant diagrams;

The distributions of normal and tangential stress components according to the Euler$-$Bernoulli flexural solution and the Jourawski shear solution;

The Von Mises equivalent stress $($limit yield stress $235$MPa $).$

Cross$-$section properties:
