It is about 15,000,000 psi (103 GPa)
Yes
They are one and the same
There is no formula for Youngs Modulus. Young's modulus is the slope of the linear part of a stress-strain diagram, so it is basically a test result. It can be thought of as a material constant related to rigidity of the material. For a high Youngs modulus, high load (stress) causes little deflection (strain).
the dimensions of Young's Modulus of Elasticity = (M).(L)^(-1).(T)^(-2)

what is the youngs modulus of copper wire
It is about 15,000,000 psi (103 GPa)
Yes
It depends on the formualtion, but a typical value is 175,000 psi, or 1.2GPa
Metal is not a specific material, how is this ever going to be answered?!
why do we need to estimate young's modulus?
They are one and the same
Youngs modulus of Elasticity represents the slope of a engineering stress strain curve. This gives the relationship between an applied stress and the resulting deformation. Stress = Youngs Modulus * strain Where strain= (Change of dimension in the direction of force) / (Original dimension magnitude) In mild steel the modulus can vary from 190-210 GPa depending on the process the steel was formed by.
It is 3.667 Mpsi
