1. A steel alloy, which has a plane strain fracture toughness of 35 MPa(m)$^{1/2}$ is exposed to a service stress of 874 MPa. Is fracture predicted if it is known that the largest surface crack ($2a = 4$ mm) in length? Assume $f = 1$.

A specimen of a 4340 steel alloy with a plane strain fracture toughness of $54.8 \mathrm{MPa} \sqrt{\mathrm{m}}$ $(50 \mathrm{ksi} \sqrt{\mathrm{in.}})$ is exposed to a stress of $1030 \mathrm{MPa}$ $(150,000 \mathrm{psi}) .$ Will this specimen experience fracture if it is known that the largest surface crack is $0.5 \mathrm{mm}(0.02 \text { in. })$ long? Why or why not? Assume that the parameter $Y$ has a value of 1.0.
A specimen of a 4340 steel alloy with a plane strain fracture toughness of $54.8 \mathrm{MPa} \sqrt{\mathrm{m}}(50 \mathrm{ksi} \sqrt{\mathrm{in}}$.) is exposed to a stress of $1030 \mathrm{MPa}$ (150,000 psi). Will this specimen experience fracture if the largest surface crack is $0.5 \mathrm{~mm}$ (0.02 in.) long? Why or why not? Assume that the parameter $Y$ has a value of $1.0 .$
An aircraft component is fabricated from an aluminum alloy that has a plane-strain fracture toughness of $40 \mathrm{MPa} \sqrt{\mathrm{m}}$ (36.4 ksi \sqrt{in.). It has been deter- } mined that fracture results at a stress of $300 \mathrm{MPa}$ (43,500 psi) when the maximum (or critical) internal crack length is $4.0 \mathrm{~mm}$ (0.16 in.). For this same component and alloy, will fracture occur at a stress level of $260 \mathrm{MPa}$ ( 38,000 psi) when the maximum internal crack length is $6.0 \mathrm{~mm}(0.24$ in.) $?$ Why or why not?
