A wire 4.5m long and having across-sectional area of 0.1m is hung by amass of 2500kg if the extension in length is 0.04m cdalculate A- strain B- stress c- young modulus

a) Strain=extension divided by original length
you will get 0.0088.
b) Stress= Force divided by area
You will get 250000
c)Modulous= Stress divide by strain
You will get 28000000
