Cylindrical stress states
WebStress is generally defined as force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. … Webstress must be less than allowable stresses outlined in material sections. Further, it states that the maximum primary mem-brane stress plus primary bending stress may not exceed 1.5 times the allowable stress of the material sections. In other sections, specifically Paras. 1-5(e) and 2-8, higher allowable
