formula od ultimate strength
here F = 5450 N
A = resiting area
the maximum stress will be at the least area resisting the force it also depends on the direction of the tensile force
for condition 1
resisting area = (22 - 12.5)*2 = 19 mm2
thus
for condition 2
resisting area = (22 - 2*4.8)*2 = 110.8 mm2
thus
