properties of materials - help

[bantamm]

for an assignment, i have to find :
youngs modulus
yield stregth
ultimate tensile strength
stress at fracture

of 0.11% carbon steel & aluminium


now, can anyone help my on the formulae for these equations??

example,

for young modulus, i am usinf e2-e1 and j2-j1.
is this correct, as my answers come out pretty low, should they be added.


and for yield strength i get an answer of 299 x 10^6 mPa. cant be right can it??
