connecting rod for am I. C. engine Q.5. Design a connecting running at 1800 rpm and developing a maximum pressure. of 3.15 N/mm. The diameter of the piston is 100mm; mass of the reciprocating parts per cylinder 2.25kg; Length of connecting rod 380mm; stroke of piston 190mm and compression ratio 6:1. Take a facture of safely 6 for the design. Take lengths to diameter as 1.3 and small end eud ratio for big bearing at 2 and Pressures bearing the corresponding bearing 10 N/mm and 15 N/mm. The density as 101 of material of the rod m may be taken as 8000 kg/m and the allowable stress in the bolts as 60 N/mm2 and in cap as 80 N/mm. The rod is to be of 1 - section for which Properties.. you I can choose your own Draw a neat dimensioned sketch showing provision for lubrication. Use Rankine formulare for which the be taken as 320N/mm2 -numerator constant may and the denominator constant 1/1500
