F b = The computed stress in the beam in bending M = The maximum moment acting on the beam Z x = The Plastic Section Modulus in the x or strong axis Z x is similar to the Section Modulus of a member (it is usually a minimum of 10% greater than the Section Modulus) (in 3) F b = The allowable stress of the beam in bending F y = The Yield Strength of the Steel (eg 36 ksi, 46 ksi, 50 ksi)Allowable Stress (Strength) The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength)Similarities between yield strength and ultimate strength For highly brittle materials, yield strength and ultimate strength are also same (plastic deformation of brittle materials is negligible) Both are basically measurement of stress Both are measured in same unit (N/mm 2) The Uniaxial Yi
