The application helps to calculate the allowable loads or span, strength calculation. Allows you to choose the material of the loaded beam, type and shape of the section.

The application will be useful for preliminary and "rough" calculations, as well as for educational purposes when studying the discipline of resistance to materials.

Designations used in the application:
P - concentrated load (kgf);
q - distributed load (kgf / meter);
σ is the allowable stress (kgf / cm²);
W is the moment of resistance to bending (cm³);

Designations in steel grades:
(n) - normalized steel;
(y) - improved steel;
