-When a component is subjected to axial stress the normal stress σn is maximum if cos θ is maximum or always one. 
-Axial stresses are the stresses, which will try to bring change in dimension of the body caused by the applied forces, which might either be of compressive or tensile in nature. The stresses caused will be termed as the axial stresses.
-Axial stress is defined by Eq. (4.64):(4.64)σa=FeAs+σbwhere σa=total axial stress (psi), Fe=effective tension/compression (lbf), As=cross-sectional area (in. 2), σb=bending stress (psi).
