A copper wire or length 2.0M, with crosssectional area 7.1x10^6 m^2 and youngs modulus of 11x10^10 N/m^2 has a 200 kg load hung on it. what is its increase in length?
F/A=Y* change in L/Length
= (200*9.8)/7.1x10^6=11x10^10* delta L/2m? am i even setting this equation up right?

Yes, you set it up correctly, and the right numbers are there. Just solve for delta L
