  - Calculation and graphical plotting diagrams of shear forces ;
- Calculation and graphical plotting diagrams of bending moments ;
  - Calculation and construction of beam deflection diagrams;
  - Display the results of internal forces in tabular form ;
  - Save the results to a PDF file;
- Save and load file sheme;
