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 4 when 52.0% of the crack length is removed.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
