4) The radii rA, rB, rC & rD are calculated .. rA = rB = Sqrt ((55-18,9)^2 + 25^2 ) = 43,9
rC = rD = Sqrt (18,9^2 + 25^2 ) = 31,34
5) The angles θA, θB, θC & θD are calculated .. θA = θB = tan-1 ((55-18,9)/ 25 ) = 55,29o
θC = θD = tan-1 ((18,9)/25 ) = 37o...
6) The direct shear stress on the area = Force /Area τ S = 5000/565,5 = 8,84 N/mm2
7) The Moment on the weld group = Force .distance to centroid M = 5000.(100+18,9) = 5.94.105Nmm
8) The Unit Polar moment of inertia of the weld group = Ju = 0.707.5.(8.b3 +6bd2+d3)/12 + b4/(2b+d)
τ RA = τ RB=48,59 N/mm2
τ RC = τ RD = 45,56N/mm2
