To find the Young's modulus of steel or any other material you require a plot of it's deformation response to loading. Specifically it's axial stress vs axial strain.
From this you need to find the gradient of the straight line portion of the curve where the material is behaving elastically and obeying Hooke's law. This is essentially stress / strain and gives you Young's modulus.
by applying stress
>
A measure of a materials stiffness.
Essentially, apply a tensile load (without exceeding the elastic limit of the material) and measure the increase in length, then apply data to:
Youngs modulus (of elasticity) E = tensile stress (pressure) / tensile strain (proportional deformation)
Where tensile stress (pascals) = load (newtons) / cross sectional area of sample (square metres)
tensile strain (no units) = extension (metres) / original length (metres)
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.
About 28,000,000 psi for stainless steel, 29,000,000 psi for alloy steel, 30,000,000 psi for carbon steel
Approx 200Gpa or 30,000,000psi check here: www.matweb.com
1. Look it up in a table.
2. Look at the slope of the linear portion of the stress vs. strain curve. This slope is the modulus.
About 30,000,000 psi ( 200 GPa) - same as most other steels, whether hardened or not.

Metal is not a specific material, how is this ever going to be answered?!
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.

Young's modulus is stress/strain. So if the modulus is high, it means that the stress value is greater compare to that of the material where the modulus is low. or in other words, the strain is very less compared to that of the material having low Young's modulus. So it tells that, if a material has high Young's modulus, the material requires more load for deformation of shape (within elastic limit).
One inaccuracy can be that the wire or material that you are using to find Young's Modulus has some impurities and there may be a slight variation in the cross sectional area so a shorter piece of that material should be used.
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.
young modulus remain unaffected ...as it depends on change in length ..
I think you mean "What variables affect young's modulus". Obviously not an english major!
Most riot shields list the material of construction as Lexan, the trade name for the polycarbonate polymer. The young's modulus of polycarbonate is 2.0-2.4 GPa (gigapascals).
