Q.1. In a creep test, a material with E = 600 MPa is initially loaded with a stress o, = 297 MPa. 1.5 hr after the initial loading, the strain in the material is measured to be 0.12, and after another hour, it is found to be 0.1832. What will be the strain in the material 3 hours after the initial %3D loading? How much time did it take for the strain to reach a value of 0.001?
