I have a 120mmx55mm c-shape beam form using a 4.5mm thick mild steel plate UTS=400MPa, on the flange it has an rectangular cut of 110mmx43mm, if this beam is subjected to a tensile force of 1150kg, what is the stress concentration factor? I need to know whether the beam can achieve a safety factor of 5 and if the beam is under torsion, what is the minimum torque if the safety factor to be 5.
beam cross section area = 968mm^2
beam cross section area at cutting = 775mm^2
beam cross section area = 968mm^2
beam cross section area at cutting = 775mm^2
