Question details

To assess winter effects, a steel beam ABC of circular cross-section was tested i as shown in Figure 1.3. The diameter of the beam was 50mm with Young Modulus, E=200GPa and coefficient of thermal expansion, α = 11.9x10-6 / o C. An axial load P = 100kN was applied to the beam as shown and then the temperature of the beam reduced 20o C. Determine the normal stress in segments AB and BC of the beam.
