Critical Buckling Load on Connecting Rod Considering Factor of Safety Formula

Critical buckling load on connecting rod = Force on Connecting Rod*Factor of Safety for Connecting Rod
PC = Pcr*fs

Critical Buckling Load

The strength of a slender structure can be reduced by the risk of buckling or other instability phenomena. Arranging for the loads in the structure to be carried as compressive loads also makes good use of the material The critical buckling load is independent of the strength of the material. This means that, when designing slender structures in which the risk of buckling determines the load-carrying capacity, it does not help to choose an alternative material having higher structural strength.

How to Calculate Critical Buckling Load on Connecting Rod Considering Factor of Safety?

Critical Buckling Load on Connecting Rod Considering Factor of Safety calculator uses Critical buckling load on connecting rod = Force on Connecting Rod*Factor of Safety for Connecting Rod to calculate the Critical buckling load on connecting rod, Critical buckling load on connecting rod considering factor of safety is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the rod will deflect laterally. The critical load puts the rod in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. Critical buckling load on connecting rod is denoted by PC symbol.
