t
If we substitute expression (2.15) into (2.10), we obtain the
calculation formulas for this case also. The result is presented
in Chapter V, relation (5.89).
Example 2.1. Find the .thermal stresses in the disk, assuming
n=1I and -it .14
As a result of calculation, we obtain
r=a; z,=O; = -Ea'o.0,.%; r= I; I,=r ; 0.;EaAt0.,13.
A stress diagram is shown in Fig. 2.1ob. The crosshatched lines
show the stresses if a = 0.

relative to the axis of the cylinder and does not change in
direction of its
