Consider a mild steel specimen with yield strength of 43.5 ksi and Young's modulus of 29,000 ksi. It is stretched up to a point where the strain in the specimen is 0.2% (or 0.002). If the specimen is unloaded (i. e. load reduces to zero), the residual strain (or permanent set) is: 0.05% 0.1% 0% 0.2%
