Young's modulus is defined as the ration of stress to strain for a given material below the limit of proportionality (the elastic limit). So Young's modulus is calculated by the formula: Stress/Strain is equal to young's modulus. Stress is defined as the force per unit area of cross-section below the limit of proportionality. So the formula is: Force (in newtons)/ Cross sectional area (in square metres). This would give the units Newtons per square metre which is written Nm-2 which is exactly the same as the Pascal (Pa); either can be used. Strain is defined as the fractional change in length produced when a body is subjected to stress. It's formula is: Change in length produced (in metres)/ Original legth (in metres). There are no units as it is a ratio of two values that have the same unit. So Young's Modulus has the formula: (Force/area)/(change in length/original length). This can be simplified to Stress/Strain (the amount of stress a body has to undergo to produce a certain amount of strain. The unit for stress is the Pascal (Pa) and there are no units for strain so overall, the unit for Young's Modulus is the Pascal (Pa) or Nm-2.

∙ 15y agoThere is no formula for Youngs Modulus. Young's modulus is the slope of the linear part of a stress-strain diagram, so it is basically a test result. It can be thought of as a material constant related to rigidity of the material. For a high Youngs modulus, high load (stress) causes little deflection (strain).

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 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 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).

What will be the poison ratio and youngs modulus for S275JR EN10025?
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
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 value of Youngs modulus for the metal?
Metal is not a specific material, how is this ever going to be answered?!
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.
Relation between youngs modulus and modulus of rigidity and poisson's ratio?
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
