When subjected to a force of compression, the length of a bone (compression Young's modulus 9.4 x 109 N/m2, tensile Young's modulus 1.6 x 1010 N/m2) decreases by 3.7 x 10-5 m. When this same bone is subjected to a tensile force of the same magnitude, by how much does it stretch(adsbygoogle = window.adsbygoogle || []).push({});

Ok after carefully looking at this problem I realized that the formula that would apply here would be

F = Y (delta L/ L0 ) A

Where y = young's Modulus Delta L = change in length and A = cross sectional area. But after looking at this problem I realized that there is no cross sectional area given, therefore I'm thinking that it is just a proportional problem.

It seems like I'm making this problem a bit harder then it actually is. Perhaps I'm missing something important?

I know that Tensile force is opposite Compression but in this case the answer would not just be the negative change in length right?

Please help
