SUMMARY
The discussion focuses on calculating the factor of safety for a bolt subjected to shear and tensile stresses. The bolt has an ultimate tensile strength of 500 MPa and a shear strength of 300 MPa, with a diameter of 8 mm. The calculated shear stress is 54.7 MPa, resulting in a shear factor of safety of 5.48, while the tensile stress is 94.7 MPa, yielding a tensile factor of safety of 5.27. It is emphasized that tension and shear should be considered together, and the relationship between shear and tensile strengths is not linear but rather parabolic or elliptical, as per Eurocode standards.
PREREQUISITES
