What is the young modules

Answer» Young’s Modulus\tYoung’s modulus is derived from the name of the scientist who defined it.\tIt is the ratio of longitudinal stress to longitudinal strain.\tIt is denoted by Y.\tMathematically:\tY= longitudinal stress/ longitudinal strain = σ/ ε\t= (F/A)/ (ΔL/L)\tY=FL/ΔL\tIf Young’s modulus is more, to produce a small change in length more force required.\tS.I. Unit is N m–2 or Pascal (Pa).\tMetals have comparatively greater Young’s Modulus. To change the length of metals, greater force is required.
