A pipe of Aluminum alloy is subjected to a tensile force F along its longitudinal axis. The pipe has an initial length of 1.2 m, an initial thickness t=1 mm and an initial outer diameter do= 10 mm. The mechanical properties of the alloy are: Modulus of Elasticity E = 75 GPa Yield stress YS = 350 MPa If a force F=12 kN is applied to the pipe, the length of the pipe becomes L=1.2282 m. Determine the permanent length of the pipe after removing the force. do F
