The fracture strength of glass may be increased by etching away
a thin surface layer. It is believed that the etching may alter the
surface crack geometry (i.e. reduce crack length and increase tip
radius). Calculate the ratio of the etched and original crack tip
radii if the fracture strength is increased by a factor of 10 when
60% of the crack length is removed.
