live through light, space, and experience, for all to peacefully enjoy and remember or Young's modulus is the ratio of stress to strain Within the elastic range below the proportional limit, this ratio is a constant for a given piece of wood, making it useful in static bending tests for determining the relative stiffness of a board The modulus of elasticity is normally measured in pounds per square inch (psi) and is abbreviated as MOE or E Values for E relating to wood Young's modulus E {\displaystyle E}, 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 σ {\displaystyle \sigma } and axial strain ε {\displaystyle \varepsilon } in the linear elastic region of a material and is determined using the formula: E = σ ε {\displaystyle E={\frac {\sigma }{\varepsilon }}} Young's moduli are typically so large Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus. In order to model such materials, Young's modulus, E (or G) can be used to describe the stiffness at a fundamental level, but we also need a simple measure of internal damping. The specific damping capacity , usually given the symbol Ψ, is just what is required.

Here, 9 / 4 = 2 and 9 % 4 = 1. In your example: 5 divided by 7 gives 0 but it remains 5 (5 % 7 == 5). Young’s modulus (E) is defined as the ratio of the stress applied to the material along the longitudinal axis of the specimen tested and the deformation or strain, measured on that same axis. Young’s Modulus is also known as tensile modulus, elastic modulus or modulus of elasticity.

The reciprocal of the bulk modulus is called the compressibility of the substance. The amount of compression of solids and liquids is seen to be very small.
