Young's modulus, the Young modulus, or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. It quantifies the relationship between tensile stress (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material and is determined using the formula:

The elastic moduli for coal ranged from 2×10 6 to 6×10 6 psi. The elastic moduli for rocks ranged from 4×10 6 to 9×10 6 psi. Their early conclusions were:1. Horizontal stresses can exceed the vertical stress by a factor of three or more. 2. σ H =2.3 σ v in reverse faulting regions. 3. σ H =1.6 σ v in strike-slip faulting regions. 4.
