In the case of the

off-center acting of longitudinal force, the stresses are determined from the

dependence:

combined bending and tension or compression, has the following form:

The strength condition

of the beam, which is working on

The combined stresses

is called such a stress state of

building that can be replaced by a combination of the simplest kinds of

deformations

In the case of

simultaneous bending and twisting, a

ccording to the third theory

of strength, we get:

This formula is:

the strength condition for a beam, which is working on combined bending and tension or compression

100%✨

the strength condition for a beam, which is working on combined bending and torsion

the strength condition for a beam, which is working on

the off-centre acting of force of tension or

compression

the strength condition for a beam, which is working on a complex bending

The condition of the neutral axis for a beam, which is working on complex bending , has this form:

In the case of the

off-center acting of longitudinal force, the c

onditions strength of materials

with tensile resistance is written as follows:

In strength of materials we have four types of a combined stresses
