25 ++ yield point force extension graph 319625-Yield point force extension graph
⇒ This graph shows a stressstrain graph for copper It looks like the forceextension graph shown earlier, but this graph will be valid for ANY sample of copper ⇒ OP on the graph represents the range of tensile stree for which the copper obeys Hooke's law The gradient of this section is the Young modulus for copper· yield point · · The area under a Force –extension graph or To plot a graph like this, measurements of extension need to be taken when adding weights to a material and when removing them After plotting a graph like this, the work done to stretch the material is the area under the loading curveOr the amount of stress in a solid at the onset of permanent deformation The yield point, alternatively called the elastic limit, marks the end of elastic behaviour and the beginning of plastic behaviour Physics Question New Spec Help The Student Room Yield point force extension graph
