A pipeline with аn оutside diаmeter оf 440 mm аnd a wall thickness оf 8 mm is pressurized to 2.6 MPa. Due to thermal expansion, a compressive force of 30 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.
