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
I think you mean "What variables affect young's modulus". Obviously not an english major!
To find the Young's modulus of steel or any other material you require a plot of it's deformation response to loading. Specifically it's axial stress vs axial strain. From this you need to find the gradient of the straight line portion of the curve where the material is behaving elastically and obeying Hooke's law. This is essentially stress / strain and gives you Young's modulus.
Young's modulus is determined experimentally by applying tensile strain (pulling on the ends) to a number of samples of the material under investigation and plotting the strain versus the elongation and taking the slope of the central part of the plot.
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's modulus
A standard specimen is loaded on a tensile test machine; load,P, is applied and measured with a load cell and strain, e, is measured with a strain gauge extensometer. In the linear region, load is divided by specimen area to get stress, s, and the modulus, E, is determined from Hooke's law, where E = s/e
Well this entirely depends on the "type" of glass you are talking about and whether its a sample or an artefact/material. as Youngs modulus = stress / stran..... where the ratio is constant. stress being sigma and strain being epsilon. If its just glass as in general (material) then its around 65 - 90 GPA . not MPA as GPA is for stiff materials. the justinator
Youngs Modulus

Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant 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).
