- Big end and big end bearings are of split type
- Big end is in an oblique direction to reduce the width of big end, reduce the load on bolts and increase the crankpin diameter
- Top end is having bush type bearing
- Rectangular or I-shaped is expensive to manufacture but necessary to resist high transverse inertia whip load, gas loads and to fulfill the weight to strength requirement
- Connecting rod is forged from Magnesium Molybdenum.
- Edges are serrated
- It is subjected to high compressive and low tensile bending stress as well as of axial type
- It connects crank pin direct to gudgeon pin
Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole is lesser in size than the corresponding circular hole. More over it is prime concern to have a smoothed generous radius at the corners to eliminate stress concentration. Hence other geometrical shapes like rectangle and square are ruled out. To compensate for the loss of material in the shell due to opening, a doubler ring has to be provided around the opening. The thickness of the ring depends on the axis length along the dirrection in which the stresses are maximum and the thickness of the shell. It is important to align the minor axis along the length of the vessel, as the stress in this direction is maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t= thickness of the shell plating Circumferential stress: Pd/4t More over a considerable material and weight saving is achieved as minor is along the direction of maximum stress.
