The car drive shaft is an automotive part that transmits the torque and rotation. It auto drive shaft usually connects the other components of the engine which isn't possible to connect directly due to the distance. As a torque carrier, this automotive component faces torsion and shear stress, which is equal to the difference in load and the input torque. Therefore, it should be strong enough to bear all the stress at the same time avoiding additional weight that could increase its inertia. In order to allow variations in the alignment among the driving and driven spare parts, auto drive shafts regularly assimilate one of the universal joints.
