The young modulus of a material is a constant. It CANNOTbe changed.
The young modulus E of a material is given by:
E = Fl/Ae
where
F is the force acting on the material
l is the length
A is the cross-sectional area
and e is the extension of the material
This formula applies ONLY when the proportionality limit is not exceeded.
One might expect that changing either one of F, l, A or e will change E. In fact, what happens is that another quantity changes so as to keep young modulus constant.
For example, when the force F is increased, the extension e increases by the same factor (Hooke's law) such that E remains constant.
You will see that whatever quantity(ies) you wish to change, the Young modulus of the material will remain constant.

What does it mean if you have a high value for youngs modulus 8333.3 compared to a low value 1200?
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).
What are the sources of errors in youngs modulus experiment?
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.
What is the amount of stress applied to a material divided by the elastic strain caused by that stress called?
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.
What will happen to youngs modulus of steel if radius is doubled?
young modulus remain unaffected ...as it depends on change in length ..
Does stress depends on youngs modulus?
I think you mean "What variables affect young's modulus". Obviously not an english major!
What is the value of Youngs modulus for the metal?
Metal is not a specific material, how is this ever going to be answered?!
What is the coefficient of a materials elasticity?
Young's modulus
What are the different types of modulus elasticity?
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
What is the material poisson ratio of Epdm?
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.

What is the Youngs Modulus of the Polycarbonate used in concave Riot shields?
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).
