Thickness of Big End Cap of Connecting Rod given Bending Stress in Cap Formula

Thickness of Big End Cap = sqrt(Inertia Force on Bolts of Connecting Rod*Span Length of Big End Cap/(Width of Big End Cap*Bending Stress in Big end of Connecting Rod))
tc = sqrt(Pi*l/(bc*σbbig))

Determination of thickness of cap

The thickness of the big end cap (tc) may be determined by treating the cap as a beam freely supported at the cap bolt centers and loaded by the inertia force at the top dead center on the exhaust stroke. This load is assumed to act in between the uniformly distributed load and the centrally concentrated load
