Chuck;
Yes what you say is true, but won't you agree it is "Also True" that the more surface area you have in contact to resist a force there will be "Less" plastic deformation. In the case of the same hinge joint with & without a well fitted doll's head, does not the one having the D'H ofer more area to handle that force & would thus go longer before plastic deformation became a problem. Also will you not agree in resisting a force it is virtualy alway better if that force can be "Resisted" from "Both Sides" rather than offset to "One Side Only".
