SUMMARY
The discussion focuses on calculating the tensile stress, shear stress, and factor of safety (FOS) for a bolt under specific loading conditions. Key parameters include a tensile strength of 460 MPa, shear stress of 280 MPa, a bolt diameter of 8 mm, and a force of 9 kN applied at an angle of 50 degrees. The participant, Ben, received feedback indicating errors in unit conversion and bolt area calculation, while confirming that the force breakdown into shear and tension components was correctly approached. Additionally, it was emphasized that bolts subjected to simultaneous shear and tension are weaker than when these loads are applied individually, necessitating a different calculation for the overall safety factor.
