The value for the cleavage plane (100) is 38 GPa and the value for the cleavage plane (001) is 33 GPa.
Young's modulus "E" is not specific to geometry of the shape in question but is specific to the material used. e.g. E = 29,000,000 psi for steel; 10,000,000 psi for T6061 aluminum; etc. The Moment of Inertia "I" is related to geometry of the shape in question and specific to the material. An HSS of a specific size will have a unique moment of inertia, I, specific to its size. TIP: by increasing the height of the HSS in its principle access, you will non-linearly increase the moment of inertial usually by height cubed thereby making the member less prone to deflection (in other words making it stiffer). Young's modulus applies to whether I make the member out of steel, aluminum, titanium etc. but not its shape
Type your from the hook's law, stress is directly proportional to the strain under the elastic limits. σ α ε where, σ - tensile stress. ε - strain. now σ =E ε where, E is the proportionality constant or the young's modulus of the material. the extension of the hook's law where the shear stress is directly proportional to the shear strain. ζ α γ ζ - shear stress. γ - shear strain. ζ = Gγ where G is the modulus of rigidity. A pure shear stress at a point can be alternatively presented by the normal stresses at 450 with the directions of the shear stress. σ1 = -σ2 = ζ. using this principle you get G = E/(2(1+ ν)) is the 1 equation. where, ν is the poisson's ratio.this is the basic relation between E,G, ν. the change in volume per unit volume referred to as the dilation. e = εx + εy + εz the shear strains are not taken into account because they do not contribute to any volume change. for an isotropic linearly elastic materials for use with Cartesian coordinates εx = σx/E - νσy/E - νσz/E similar equations are formed for εy ,εz . e = εx + εy + εz = ((1 - 2ν)/E)( σx+ σy+ σz) if σx= σy = σz = -p like a hydrostatic pressure of uniform intensity then -p/e = k = E/3(1 - 2ν) is the 2 equation where k is the bulk modulus. Addin 1 & 2 by bringing only the poisson's ratio to left side and taking all other constants to the right side the equation formed is the 9/E = 3/G + 1/k is the relation between the three modulus. here...

No, stress is not a dimensionless quantity. By application of a simple equation of stress, axial stress, we can determine the primary dimensions (Length, Time, Mass, Etc.) of stress.Stress (sigma) = Force (F)/Area (A)Force has the primary dimensions of: (Mass*Length)/Time^2Area has the primary dimensions of: Length^2Therefore we can determine that Stress has the primary dimensions of: Mass/(Length*Time^2)Common units include: Newtons (SI), psi (pounds mass per square inch)You may have confused stress with strain. Strain has primary dimensions of Length/Length and therefore it is often expressed without any attached units.
Metal is not a specific material, how is this ever going to be answered?!
Young's modulus
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.
Youngs Modulus

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).
