WebThe program uses this factor to calculate the axial force from a given torque. For a bolt WITH a nut, torque is applied on the nut. F = T/ (K*D) For a bolt WITHOUT a nut, torque is applied on the head. F = T/ (K*D*1.2) Where F = the axial force in the bolt, T = applied torque, K = friction factor, and D = major diameter of the shank. WebFactors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1). where . FOS = Factor of Safety. F fail = failure load (N, lb f) . F allow = allowable load (N, lb f) . Example - Structural Steel Column in a Building. Due to buckling the failure load of a steel column in a building is estimated to …
