Thank you for the opportunity to help you with your question!

Y= FL0/ADL

Y=8 *10^10

A=2 *10^-5

F=190*10

L0=3.70

putting the values 

change in Length (DL) = (190*10*3.70)/(2.00*10^-5)(8*10^10)

=4.39*10^-3 m

Please let me know if you need any clarification. I'm always happy to answer your questions.
