9. Maksimālā momentālo vertikālo pārvietojumumu noteikšana
u_max=5/384 (q_k*L^4)/(E_1*I_y )=0,013 (11,85*〖5,7〗^4)/(1,2*10^7*144982*10^(-8) )=0,00934m=0,934cm=9,34mm
γ_f=1,35;
q_k=q_d/γ_f =16/1,35=11,85 kn/m

Atbildes
σ_max=1,8065 kN/〖cm〗^2 =18065 kN/m^2 =18,065 mPa=18,065 N/〖mm〗^2

τ_max=0,242 kN/〖cm〗^2 =242 kN/m^2 =2,42 mPa=2,42 N/〖mm〗^2

u_max=0,00934m=0,934cm=9,34mm
