How many pounds can steel lift?
Well, metal steel can lift an infinite amount of weight if necessary, BUT it can only withstand tensile PRESSURE up to a certain amount. That amount depends on what kind of steel you have; you can have low and high carbon steel, for example, here are some maximum tensile forces a lot of common steels can withstand: Coated Steel (Galvanized): 200-215 GPa Terne Coated Stainless Steel: 189 - 197 GPa Terne Coated Steel: 185-200 GPa AirMet100 High alloy steel: 193-203 GPa AF1410: 203 -213 GPa 17% Cobalt Steel: 199-209 GPa 36% Cobalt Steel: 199-209 GPa 6% Tungsten Steel: 218-229 GPa A-286: 201-211 GPa N-115: 201-211 GPa 250 Maraging Steel: 183 - 192 GPa 280 (300) Maraging Steel: 183-192 GPa And that's just Coated and High-alloy steels, I have yet to go through Cast Irons, Commercial-purity Iron, Low alloy steel, low carbon steel, medium alloy steel, medium carbon steel, stainless steels, tool steels, and very low carbon steels, and I'm not even sure if this is a complete list of the different types of steels in the world. TL;DR We need more information. EDIT: By pressure, I mean the negative tensile type of pressure. EDIT 2: At it's thinnest point, most supportive skeletal features will be able to support 132 pounds quite easily. However, if you want to make an effective light-weight strong skeleton, I would suggest using aluminium rather than steel.
much too vague. Need the shape and thickness of the steel, where it is supported, and where the load is placed.
It depends on the type of steel and the geometry of the item.
I think that you failed to put up a meaningful question. I suggest that you try again and seek help.
