An aluminum oxide component must not fail when a tensile stress of 16.5 mpa is applied. determine the maximum allowable surface crack length if the surface energy of aluminum oxide is 0.90 j/m2. the modulus of elasticity of this material is 393 gpa.

90 per square surface of the inner difference between both.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
