Significance of crank-web in IC-Engine.

The crank-web in an IC engine plays a critical role by:

1.Transferring Force: It acts as a sturdy arm, transmitting the reciprocating piston force (up/down) from the connecting rod to the crankshaft.

2.Converting Motion: This force is converted into rotational motion by the crankpin journalling on the crankshaft.

3.Handling Torque: The crank-web endures the twisting force (torque) generated by the combustion pressure acting on the crankpin.

4.Strength & Stiffness: Its design ensures the crankshaft maintains rigidity, resisting bending moments that could cause stress and fatigue.

In essence, the crank-web is the bridge between the pistons and the rotating crankshaft, enabling power transfer and crankshaft stability.
