I have built several tractor-mounted boom extensions and now I want solid, engineer-backed numbers on exactly how much weight each point along the boom can safely handle. The boom is welded from a 3/8" side-steer plate and a 2-1/2" × 2-1/2" × 3/16" square tube. From the plate it runs straight for 10 ft, then kicks up at a 30° angle and continues another 2 ft, giving a total length of 11 ft 10 in. Its primary job is lifting pole-barn trusses, so the working load will sit in the 500–1,000 lb range. I don’t have to satisfy OSHA, ISO, or any other formal standard, but I do want a clear, defensible safety factor. What I need from you is a straightforward structural analysis—hand calculations, FEA, or a mix—that tells me: • Ma...

Summary We are developing a perfusion lid system for a proprietary vertical-membrane co-culture plate used for advanced cell culture. The lid will enable controlled flow (shear) along the membrane and will scale to the full plate with 12 independent recirculating loops (one loop per column). Each column contains 8 wells (total 96 wells). We prefer 12 independent loops so each column can run different flow rates and/or media conditions. We are looking for a contractor who can support development (concept → CAD → prototype strategy → DFM), not just drafting. We want flow constrained into a defined gap near the membrane to generate predictable laminar shear Target design gap: ~0.3–0.5 mm (must be toleranced and verifiable) Typical target per-well flow range: ~30–20...
