From 110 - 130 Gpa
A value that cannot be physically measured. It's a value known only in theory. (such as the size of a graviton)
Beech counts as a hardwood tree, for it has flowers. The distinction between hardwood and softwood is a poor one, and really is between Angiosperms and Gymnosperms. For example, Balsa wood, one of the softest and lightest woods is classified as a hardwood because it flowers.
its absolute value is greater than or equal to 1 and less than 10
Salicylic acid is also known as 2-Hydroxybenzoic acid. The literature Ka value is 2x10 to the negative 14th power. Which makes salicylic acid a somewhat strong acid.

Metal is not a specific material, how is this ever going to be answered?!
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 modulus for brass is 91*109 Nm-2

The absolute value or the modulus.
Young's Modulus (modulus of elasticity) describes the stress-strain behavior of a material under monotonic loading. The dynamic modulus of elasticity describes the same behavior under cyclic or vibratory loading.
When we talk about deformatation, we are referring to two properties, namely Elasticity and Plasticity. These properties are measured using constants known as " Moduli of Elasticity". There are 4 such moduli: Young's Modulus Axial Modulus Rigidity Modulus Bulk Modulus The larger the value of the Bulk Modulus, the harder it is to compress the material.
The Young's modulus of spider silk is 1 E10 Newton's per square meter. Comparatively, the modulus of high tensile steel is only 2 E11 Newton's per square meter.
Brass is an alloy and as such can very greatly in its properties depending on its content, so there is no single shear modulus for brass. The only way to be certain is to either test it your self or go by data provided by the manufacturer. If, on the other hand, you are only working theoretically 40GPa is a good estimate for brass in general. Source: http://www.engineeringtoolbox.com/modulus-rigidity-d_946.html
