They are made by bending thin sheets of carbon or low-alloy steel into almost any desired cross section.

They are structural steels which are made up mostly iron and carbon, with less than 1% carbon

It is a hot-rolled shape with two flanges and a web, with one axis of symmetry, and the inside fsced of the flanges are sloping.

It is a hot rolled shape that consists of two parallel flanges separated by a single web, has two axes of symmetry, and the outside and inside facrs of thr flanges are parallel

It is a hot rolled shape that consists of two parallel flanges separated by a single web, has two axes of symmetry, and the inside faces of the flanges slope with respect to the outside Faces.

It is the range in the stress-strain diagram where the strain remains constant, even though the strain continues to increases.

It is a hot-rolled shape that is used for bearing piles, has parallel flange surfaces, approximately the same width and Depth, and equal flange and web thickness

They are made when special conditions such as the need for heavier members or particular cross-sectional geometries

According to the NSCP which of the following ASTM specifications is approvrd to be used for plates?

Which of the following shapes CAN NOT be used when you are to use ASTM A36 Steel

The manufacturing process takes place in a mil, molten steel is taken from an electric arc furnace and poured into continuous casting system where the steel solidifies but is never allowed to cool completely, and then passes through a series of rollers that squeeze the material into the desired cross-sectional shape.

For a W shape, the preferred material specification to be used is

It is the range in the stress-strain diagram where additional load( and stress) is required to cause additional elongation (and strain)
