Young’s Modulus of Iron

An experiment is done to confirm the Young’s Modulus of iron. In the experiment, a
0.500 m
long cylindrical iron rod with diameter of
0.005 m
is compressed by applying
10000 N

-force on both ends parallel to the length of the rod. Knowing that the Young’s Modulus of iron is
21×1010 Pa
, what is expected change in length of the iron during the stress is applied? Young’s Modulus of Iron
