Elasticity is a body’s capacity to recover to its original state after being subjected to external stress and strain. If a body returns to its original configuration faster than others, it is considered to be more elastic.
- Young’s modulus defines the connection between stress and strain proportional deformation in an object. A solid object deforms when a specific load is applied thereto. If the thing is elastic, the body regains its original shape when the pressure is removed.
- If an equivalent amount of force is applied to a steel wire and to a wire made from rubber of an equivalent length and cross-sectional area, the extension of the rubber wire is simpler than the extension of the steel wire. So, it is often said that for a given amount of stress, the strain produced within the steel is relatively smaller than the strain produced within the rubber and other given materials. This means that they’re characterized by a linear relationship between stress and strain, the relative amount of deformation. To explain elastic properties of linear objects like wires, rods, or columns which are stretched or compressed, a convenient parameter is the ratio of the strain to the strain, a parameter called the “Young’s modulus” or “Modulus of Elasticity” of the fabric. Young’s modulus is often wont to predict the elongation or compression of an object as long because the stress is a smaller amount than the yield strength of the fabric.
- Among rubber, steel, wet clay, and plastic, steel has the utmost elasticity ranging between 180-200 GPA.
