STEP 1: Convert Input(s) to Base Unit

Inertia Force on Bolts of Connecting Rod: 8000 Newton --> 8000 Newton No Conversion Required
Span Length of Big End Cap: 80 Millimeter --> 0.08 Meter (Check conversion here)
Thickness of Big End Cap: 12 Millimeter --> 0.012 Meter (Check conversion here)
Bending Stress in Big End of Connecting Rod: 58 Newton per Square Millimeter --> 58000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

b_c = P_i*l/(t_c^2*σ_big) --> 8000*0.08/(0.012^2*58000000)

Evaluating ... ...

b_c = 0.0766283524904215

STEP 3: Convert Result to Output's Unit

0.0766283524904215 Meter -->76.6283524904214 Millimeter (Check conversion here)

FINAL ANSWER

76.6283524904214 ≈ 76.62835 Millimeter <-- Width of Big End Cap

Material of bolts for big end cap

The bolts and the big end cap are subjected to a tensile force which corresponds to the inertia force of the reciprocating parts at the top dead center on the exhaust stroke. The bolts may be made of high carbon steel or nickel alloy steel. Since the bolts are under repeated stresses but not alternating stresses, therefore, a factor of safety may be taken as 6.
