Hertzian contact deformations are discussed including calculations. ** 0.000005" = 0.127µm (not nm) ** #practitioner_of_the_mechanical_arts Paypal donation https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=W64WRAAGMA79J&source=url Support through Patreon https://www.patreon.com/ROBRENZ
