As the welding seam length along the skid to bottom is more than required, so it's OK!
Vertical Shear Stress Check
Fv= 100008 N
Fv=S2y x (Lf x f)
so Lf=Fv / (S2y x f)= 46.95211 mm
As the welding seam length along the skid to bottom is more than required, so it's OK!
Over Turning Force Check
Fv xL/2 + Fhc x H/2 = M x L/2 + S2y x (Lf x f) x L/2
so Lf=2(Fv x L/2 + Fhc x H/2 - M x L/2) / (S2y x f x L) = 178.2461 mm
As the welding seam length along the skit to bottom is more than required, so it's OK!
