Combined stress at the inner fiber σri = σd + σbi = 10.417+286.232
= 296.649N/mm 2 (tensile)
Combined stress at the outer fiber σro = σd + σbo = 10.417286.232
= 198.189N/mm 2 (compressive)
Maximum shear stress max = 0.5x σmax = 0.5x296.649
= 148.3245 N/mm 2 , at the inner fiber
The figure shows the stress distribution in the critical section.
