Explain the following terms related to Young's Modulus:(i) Stress(ii) Strain
Terms related to Young’s modulus or modulus of elasticity:(i) Stress: Stress is the force experienced by the unit area of a material. Stress can be characterized on the basis of the direction of the deforming forces acting on the body. Magnitude of stress = F.A = Force.area(ii) Strain: A force that stretches or affects the material and makes it reach a damaging degree. Strain = \\[\\frac {dL} {L}\\], where dL = total elongation and L = original length.
