Granite. Granite is the most common intrusive rock in Earth's continental crust, It is familiar as a mottled pink, white, gray, and black ornamental stone. It is coarse- to medium-grained. Its three main minerals are feldspar, quartz, and mica, which occur as silvery muscovite or dark biotite or both. Of these minerals, feldspar predominates ...
Feb 13, 2015· First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.
Young's modulus, the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise. It quantifies the relationship between tensile/compressive stress (force per unit area) and axial strain (proportional deformation) in the linear ...
