Yes , I managed to figure it out a few min ago. Ixx = (D (1.116) * D ^ 3) / 12 D^4 = I * 12 * 1.116 D = 4√ I * 12 * 1.116

I had tried I = bd3/12 - bd3/12 & then doing the same including the additional size of the weld. I = bd3/12 - bd3/12 and trying to subtract the smaller from the larger but that didnt work. I wrote it out a couple of times trying to calculate each rectangle individually but I couldent get...

I've to work out b & d in this equation. I=bd^3/12 I know that the ratio between b & d in this case is 1.166 and I am given the value of I. It is an engineering problem as the software will only allow the use of square/rectangular or round section but we are using H section and we are allowed...

Im needing to calculate the Zxx and Yxx for 2 shapes. The shapes are an H profile and a + profile however its not the basic profiles I am needing but the moment of inertia for the weld profile surrounding them as the theory is they are welded to a vertical metal surface then a load is applied...
