A pipeline with аn оutside diаmeter оf 420 mm аnd a wall thickness оf 10 mm is pressurized to 2.3 MPa. Due to thermal expansion, a compressive force of 32 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.
