Along the end curve the second blend's contact line on x = 40 is that curve offset 3 towards its centres of curvature. The section turns 90 degrees from (3, 0) on the top to (0, 3) on the side; with rho(phi) its radius of curvature at tangent angle phi, its setback along the top is 3 = Int_0^(pi/2) rho(phi) cos(phi) dphi, and Int_0^(pi/2) cos(phi) dphi = 1, so 3 is a weighted mean of rho; the order-2 section's curvature is 0 at both ends (rho unbounded there), so rho is not constant and its least value is below 3. The offset by 3 passes that curve's evolute and folds back on itself: the blend passes through itself (as ladder 07-fillets/016's r7 on the r5 round's arc). No such blend exists, so the right answer is a clean refusal for its size.",
