A pipeline with an outside diameter of 420 mm and a wall thickness of 12 mm is pressurized to 2.2 MPa. Due to thermal expansion, a compressive force of 21 kN is generated along the length of the pipes. Determine the normal stress along the length of the pipes. Ignore the bending stresses due to the weight of the pipes and the fluid that they contain.
