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. | |
