The stress-strain diagram for an aluminum alloy that is used for making aircraft parts is shown in Figure. If a specimen of this material is stressed to s = 600 MPa, determine the permanent set that remains in the specimen when the load is released. Also, find the modulus of resilience both before and after the loan application.
