The fracture strength of glass may be increased by etching away a thin surface layer. It is believed that the etching may alter surface crack geometry (i. e. reduce the crack length and increase the tip radius). If half of the crack length is removed, compute the ratio of the etched to the original crack radius for a four-fold increase in fracture strength.
