Why do you feel a "tube resist (sic) stress risers better than a solid cylinder?" Please state either your reason or quote your reference. You're just wrong.
Are you an engineer? It is your BS theory to prove. Have you conducted a design of experiments? Do you have a background in material science. If you understood wtf you were saying you would realize how ignorant you really are.
"The strength of a tube, or hollow cylinder, is to the strength of a solid one as the difference between the fourth powers of the exterior and interior diameters of the tube, divided by the exterior diameter, is to the cube of the diameter of a solid cylinder, - the quantity of matter in each being the same. Hence, from this it will be found, that a
hollow cylinder is one-half stronger than a solid one having the same weight of material."
FYI...it is chromoly not cromoly?
