Variables Used
Compressive Stress in Crank Web Central Plane - (Measured in Pascal) - Compressive stress in crank web central plane is the magnitude of force applied onto the crank web, divided by cross-sectional area of crank web in a direction perpendicular to the applied force.
Vertical Reaction at Bearing 1 - (Measured in Newton) - Vertical Reaction at Bearing 1 due to Crankpin Force is the vertical reaction force acting on the 1st bearing of the crankshaft because of the force acting onto the crankpin.
Width of Crank Web - (Measured in Meter) - Width of Crank Web is defined as the width of the crank web (the portion of a crank between the crankpin and the shaft) measured perpendicular to the crankpin longitudinal axis.
Thickness of Crank Web - (Measured in Meter) - Thickness of Crank Web is defined as the thickness of the crank web (the portion of a crank between the crankpin and the shaft) measured parallel to the crankpin longitudinal axis.
STEP 1: Convert Input(s) to Base Unit
Vertical Reaction at Bearing 1: 10725 Newton --> 10725 Newton No Conversion Required
Width of Crank Web: 65 Millimeter --> 0.065 Meter (Check conversion ​here)

Materials for making Connecting Rod

Connecting rods can be made from various grades of structural steel, aluminum, and titanium. Steel rods are the most widely produced and used as connecting rods. Their applications are best used for daily drivers and endurance racing due to their high strength and long fatigue life. The only problem with using steel rods is that the material is extremely heavy, which consumes more power and adds stress to the rotating assembly. Below mentioned materials are taken as connecting rod materials- Carbon Steel, High strength low alloy steel, Corrosion-resistant high strength low alloy steel, and Quenched and tempered alloy steel.

What is a Crank Pin?

A Crankpin is the part of the crank of a crankshaft to which the connecting rod is attached. Crankpins transfer up-and-down motion between the crankshaft and connecting rod. The big end of the connecting rod is connected to the crankpin of the crankshaft by way of a bearing. Connecting rods typically have two-piece crankpin bearings for connecting the lower end of the rod to a crankpin of a crankshaft. Crankpin meets the demands for high-performance engines, lightweight design, component reliability, and low through cost manufacturing. The crankpins are subjected to shock and fatigue loads. Thus the material of the crankpin should be tough and fatigue resistant. The crankpins are generally made of carbon steel, forged steel, and alloy steel. It also improves the strength of the component. The surface of the crankpin is hardened by case carburizing, nitriding, or induction hardening.
