Sheet Metal Bending: stuck on calculating the minimum radius required

WebApr 10, 2024 · To get A (effective area of the weld), first, we need to convert the leg length to the throat size. as we know a= z x 0.707 so we need to multiply the leg length as (1/2 x 0.707 = 0.3535 inches) times the length (10 inches) times 2 welds. The effective area of total weld will be : 10 in x 0.3535 in x 2 = 7.07 sq-in. We can now solve for F. WebJan 8, 2009 · Open navigation menu.
