between 0.27*1010 Pa and 0.35*1010 Pa depending on the perspex
E=2800 MPa nu=0.38 For Perspex sheet
The Young modulus and storage modulus measure two different things and use different formulas. A storage modulus measures the stored energy in a vibrating elastic material. The Young modulus measures the stress to in still elastic, and it is an elastic modulus.
The plastic in perspex (the common US name is plexiglas) is poly(methyl methacrylate).
Plastics.
The young modulus young modulus(E) = stress/strain stress = force/area strain = extension(total length)/original length It is this property that determines how much a bar will sag under its own weight or under a loading when used as a beam within its limit of proportionality

I think you mean "What variables affect young's modulus". Obviously not an english major!
young modulus remain unaffected ...as it depends on change in length ..
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
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
Metal is not a specific material, how is this ever going to be answered?!
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.
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
The Young's modulus of Teflon (PTFE) is around 500-650 MPa, indicating its stiffness and resistance to deformation under stress.
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.
