1. surface hardening
2. increased stiffness of the material
3. structural changes in the material
4. residual compression at the surface
residual compression at the surface
1. axial stiffness is less than bending stiffness
2. of absence of centrifugal effects in the rod
3. the number of discontinuous vulnerable to fatigue are more in the rod
4. at a particular time the rod has only one type of stress where as the beam has both the tensile and compressive stress
the number of discontinuous vulnerable to fatigue are more in the rod
