The connecting rod of a four stroke cycle Diesel engine
is of circular section and of length 550 mm. The diameter and stroke of the cylinder are 150 mm and
240 mm respectively. The maximum combustion pressure is 4.7 N/mm2. Determine the diameter of
the rod to be used, for a factor of safety of 3 with a material having a yield point of 330 MPa.
Find also the maximum bending stress in the connecting rod due to whipping action if the engine runs
at 1000 r.p.m. The specific weight of the material is 7800 kg/m3.
