A steel bolt has a modulus of 207 GPa. It holds two rigid plates together at a high temperature under conditions where the creep of the steel is described by the equation:ε=ε0σσ0nwhere n= 3, andε=127.8 10−×/s when σ= 28 MPa. The bolt is initially tightened to a stress of 69 MPa. What is the stress in it after 1 year? (14 MPa)
