Ans: The Yield point is the point on a stress-strain curve that states the limit of stretchability behaviour and the starting of plastic behaviour. Before the yield point, a material will deform stretchability and return to its original shape when the applied stress is removed. The Importance of the Yield Point Explained -That is essential in designing components, as it is the upper limit of yield strength that determines the load that can be applied. Yield strength helps in controlling many materials production procedures such as forging, rolling and pressing.It is also essential in constructing structures as the structures can perform in the elastic region under normal servicing conditions. A metal with a higher yield strength is strong and sustains high stress without permanent distortion. A straight line is drawn through a point at the same slope as the stress-strain curve’s initial portion to measure the yield strength. The intersection between the new line and the stress-strain curve is shown on the stress axis. The stress value is pounds per square inch.
