A creep test is done on a cylindrical part with an initial diameter of 100mm and length of 500mm. At the stress of 50 MPa and a temperature of 675°C, the steady-state creep rate is 3.2x10-4 % per hour. Find the steady-state creep elongation after 2200 hours, given that the creep deformation at that time is 5.6 mm.
