The combined bending and torsion is
A short slender bar subject to axial compression is called a
The central part of the cross-section, in which or
at its limit, the application of compressive force, causes only compressive
stresses at all points of the cross-section is called
the core of the
cross-section
Combined bending and tension or compression is the case of stresses state, when in an arbitrary cross-section internal force factors are given to the normal force and to one or two bending moments are in the perpendicular planes
For a given column the coefficient of lengthening
To ensure the stability reserve, the condition is required:
The condition of the neutral axis for a beam, which is working on complex bending , has this form:
This formula is:
For a given column the coefficient of lengthening
In strength of materials we have six types of a combined stresses
