A titanium rod of length 10 cm and circular diameter of 2 cm is pulled in tension with a load of 100000 N. The rod elongates by 0.01 cm under the load but recovers to its original length when the load is released. By how much (in centimeters) did the diameter of the rod change after the load was applied? Indicate tables or charts that you use to answer this question.
