The Engine Crankshaft is to convert the linear motion of the pistons into rotational motion. As the pistons move up and down within the cylinders, they transmit force to the connecting rods, which are connected to the crankshaft. Attributes: • To withstand the forces and stresses.• Ensure smooth rotation and minimize bearing wear.Applications: The Engine Crankshaft is used for powering the wheels by converting the linear motion of the pistons into rotational motion. It is connected to the pistons via connecting rods and transforms the up-and-down motion of the pistons into the rotational motion needed to drive the vehicle.
