IN MACHINE design modulus of elasticity place an important role. from the value of modolus of elasticity we come to know about maximum value of load that can be to the given material upto which the material is assume to follow the hook's law.
The Weibull Modulus is related to the distribution of flaws in a brittle specimen. It is important to note that it isn't relate to the size of the flaws. To find the Weibull Modulus, many samples of the same material are tested, in tension, to failure. If the flaws are evenly distributed throughout the specimen, the data from the the tests will show little statistical scatter and result in a high value of the Weibull Modulus. Conversely, if the flaws are unevenly distributed causing the test data to differ greatly from sample to sample (greater flaws means more opportunities for stress concentrations at those flaws, causing a lower failure stresses) then there will be large statistical scatter in the test data, and the Weibull Modulus will be measured as a lower number.

Value by value
9 is the value of -3 squared
10 - 20
It is about 15,000,000 psi (103 GPa)
It depends on the formualtion, but a typical value is 175,000 psi, or 1.2GPa
Metal is not a specific material, how is this ever going to be answered?!
Youngs modulus of Elasticity represents the slope of a engineering stress strain curve. This gives the relationship between an applied stress and the resulting deformation. Stress = Youngs Modulus * strain Where strain= (Change of dimension in the direction of force) / (Original dimension magnitude) In mild steel the modulus can vary from 190-210 GPa depending on the process the steel was formed by.
The value for the cleavage plane (100) is 38 GPa and the value for the cleavage plane (001) is 33 GPa.
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).
the young's modulus of aluminium is 0.675 * 105 this can also be called as the modulus of elasticity
what is the flexural modulus value od mild steel
the modulus for brass is 91*109 Nm-2
