AT SECTION A-A
Top fibres are critical.
Sn(max) = ((M*c)/I) + (P/A)
Maximum normal stress Sn(max)=49.5 MN/m^2 tensile at top fibres of section A-A
Sn(min) = -((M*c)/I) + (P/A)
Minimum normal stress Sn(min)=-31.5 MN/m^2 compressive at bottom fibres of section A-A
Maximum shear stress T(max)=24.7 MN/m^2 at top fibres of section A-A
AT POINT B
(neglecting stress concentration)
Sx = ((M*c)/I) + (P/A)
Sx=49.5 MN/m^2 tensile
Sy = ((M*c)/I)
Sy=54.0 MN/m^2 tensile
Sz=0 and Txy=0
Sn(max) =((Sx+Sy)/2) + sqrt( ((Sx-Sy)/2)^2 - (Txy^2) )
Maximum normal stress Sn(max)=54.0 MN/m^2 tensile
Sn(min) =((Sx+Sy)/2) - sqrt( ((Sx-Sy)/2)^2 - (Txy^2) )
Minimum normal stress Sn(min)=49.5 MN/m^2 tensile
T(max)=(Sn(max)-0)/2
Maximum shear stress T(max)=27.0 MN/m^2
