Whenever possible, bolts in shear should have a higher shear strength than the bearing yield strength of the materials they go through. Since the bolts have some clearance and position tolerances in their respective holes, the sheet material must yield in bearing to allow the bolt pattern to load all of the bolts equally at a given loion in the pattern. Note that the sloppier the hole ...

Highstrength, lowalloy steels (HSLA) are also often classified as lowcarbon steels, ... The molten iron extracted from the iron ore is enriched with carbon from the burning coke. The remaining impurities combine with the lime to form slag, which floats on top of the molten metal where it can be extracted. The resulting molten steel contains roughly 4 wt.% carbon. This carbon content is then ...

Shear strength is defined as the maximum load that can be supported prior to fracture, when applied at a right angle to the fastener's axis. A load occurring in one transverse plane is known as single shear. Double shear is a load applied in two planes where the fastener could be cut into three pieces. Figure 2 is an example of double shear. For most standard threaded fasteners, shear ...

 · The shear strength of a material is defined as its ability to resist forces that cause the material's internal structure to slide against itself. The shear strength of a material can be measured in either the vertical or horizontal direction. For example, if the force causes the object's layers to slide in the horizontal direction, the material will exhibit horizontal shear strength ...

 · Ironbased alloys get their strength from the addition of carbon. An ironcarbon alloy is generally produced by combining coke with iron ore and applying heat until the coke ignites. Coke is a carbonrich form of coal. As a result of this strong heating, coke drops carbons and adheres to oxygens from the iron oxides, leaving a combination of carbon and iron. This process is called reduction ...
