 Homework Statement:

A cylindrical steel specimen 350mm long is to be subjected to a tensile load of 10KN. The modulus of elasticity is 207GPA, Yield Strength is 415 MPa, and Poisson's ratio is 0.30
Determine
a)The maximum elastic elongation
b)the reduction in diameter
 Relevant Equations:

stress = Force / Area
strain = Stress / Modulus of Elasticity
Poisson's ratio = transverse stress / longitudinal stress
I was able to calculate a), and got 0.7mm
But I have no idea where to even start with b)
