Young’s Modulus (also referred to as the Elastic Modulus or Tensile Modulus), is a measure of mechanical properties of linear elastic solids like rods, wires, and such. Other numbers measure the elastic properties of a material, like Bulk modulus and shear modulus, but the value of Young’s Modulus is most commonly used. This is because it gives us information about the tensile elasticity of a material (ability to deform along an axis).
Young’s modulus describes the relationship between stress (force per unit area) and strain (proportional deformation in an object). The Young’s modulus is named after the British scientist Thomas Young. A solid object deforms when a particular load is applied to it. The body regains its original shape when the pressure is removed if the object is elastic. Many materials are not linear and elastic beyond a small amount of deformation. The constant Young’s modulus applies only to linear elastic substances.
It is defined as the ratio of Stress to Strain & is represented by letter E in MPa units.
It is defined as the ratio of the uniaxial stress over the uniaxial strain in the range of stress in which Hooke's Law holds
section modulus is a measure of the strength of a beam. The more the section modulus the more is the strength.
how does the fineness modulus of aggregate affect the strength of concrete
The tangent modulus of steel varies depending on if the steel has yielded.If the steel has not yielded, and is still elastic (stresses less than approx. 275 MPa (39885 Psi) the tangent modulus will be equal to the Young's Modulus, 205 GPa (39885367)If the steel has yielded, the tangent modulus will be related by the Ramsberg-Osgood Equation, but a reasonable value to use would be approx. 1.5 GPa (2175565 Psi)
section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. plastic section modulus is the section modulus when the cross section is subjected to loading such that the whole section is under yield load. numerically it is equal to the pdoduct of the half the cross section area and the distance of center of gravity of tension and compression area from neutral axis
Per ASTM C78, the flexural strength of concrete (or the Modulus of Rupture) can be derived from the following equation:fc' = R2 / 100where:fc' = compressive strength (psi)R= Modulus of Rupture (psi)

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!
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 value for the cleavage plane (100) is 38 GPa and the value for the cleavage plane (001) is 33 GPa.
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.
