4. Visvairāk noslogotajam stienim (ar lielāko lieces momentu) novērtēt aksiālspēka iespaidu uz normālspriegumiem.

1) no A un pa kreisi un no B un pa labi stienis (AN45=84,7 cm2 un A600x300=1800 cm2) abiem Mmax=180 kNm un Nmax=85 kN

Tērauda gadījumā:
_N=N_max/A=(85*10^(-3))/(84,7*10^(-4) )=10,04 MPa; _N/_45 =10,04/146,2=6,87%
Koka gadījumā:
_N=N_max/A=(85*10^(-3))/(1800*10^(-4) )=0,472 MPa; _N/_priede =0,472/10=4,72%
