effect on the longitudinal deformation even when the cross force
varies continuously along the axis of the beam.
6.5 Calculation for the strength under direct cross
bending
Consider the stress state at specific points of section 1 1 of the
beam (fig. 6.12).
Figure 6.12
The analysis of the correlations (6.11) and (6.18) shows that at
the extreme points 1 and 5 tangential stresses are absent and
normal stresses reach the extreme values, that is at these points
there is a linear stress state. At the points 2 and 4 at the distance y
