| YIELD POINT The load per unit of original cross section at which, in soft steel, a marked increase in deformation occurs without increase in load. |
| YOUNG?S MODULUS The coefficient of elasticity of stretching. For a stretched wire, Young?s Modulus is the ratio of stretching force per unit cross-sectional area to the elongation per unit length. The values of Young?s Modulus for metals are of the order 1012 dynes per square cm. (See Modulus of Elasticity.) |
