based on the microstructure of gray cast iron, the graphite form flakes, which is tiny flakes that tend to weaken the matrix structure in tension. it tend to fail in diagonal shear.
Iron wires, often used as reinforcement in concrete structures, enhance the tensile strength and durability of the concrete. Concrete is strong in compression but weak in tension, making it prone to cracking under stress. By embedding iron wires or rebar within the concrete, the overall structural integrity is improved, allowing the concrete to better withstand tensile forces and extend its lifespan. This combination is crucial for ensuring safety and stability in construction projects.
There are different forces on a materials such as Compression and Tension. Compression is pushing a material together. Tension is pulling a material apart. Concrete has good strength in Compression, but is weak in Tension. The steel reinforcement improves the resistance to tension of the concrete.
Cast iron is more brittle than steel primarily due to its higher carbon content, typically ranging from 2% to 4%, which leads to the formation of graphite flakes. These flakes create weak points within the material's microstructure, making it less ductile and more prone to fracture under stress. In contrast, steel generally has a lower carbon content and a more uniform microstructure, which provides greater toughness and flexibility. This difference in composition and structure is what ultimately contributes to cast iron's brittleness compared to steel.
Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding metal reinforcing bars, glass fiber, or plastic fiber to carry tensile loads
Concrete is very strong in compression but weak in tension. RCC is concrete with reinforcing steel bars in it. Steel is a really good material in tension. Steel carries the tensile load and thus RCC is strong in tension too. However, designers still try to ensure concrete is in compression wherever possible.
Steel is different from cast iron because cast iron is when some of the molten iron is left to solidify in moulds. And then most of the iron is kept molten to be turned into steel. But steel is made by removing move of the impurities from the iron and then mixing other elements to change the properties.
Weak
It depends on the iron. Iron is strong in compression, but weak in tension and bending. Its strength and stiffness deteriorate when subjected to high heat, such as in a fire. Cast iron was sometimes used as construction material in the Industrial Revolution era, period between the 18th and 19th century. This was before modern steel was developed. Also, if you actually plan on building a bridge, please consult an architect and an engineer.
Steel is made partially out of Iron, and no, they are not weak unless you stick'em up your anus
it is weak like iron and and copper

because iron keeps the body healthy. it provides you with energy and keeps you from being weak.
You can get anemia and feel weak.
That is the correct spelling of ironically.
Tachycardia, weak pulse, hypo tension, dizziness, fainting, coma and death.
