<h2>What is the drive shaft?</h2>
The drive shaft bearing other titles like prop shaft or propeller shaft is a vehicle's drive train component. Its job is to deliver torque from the transmission to the differential further transmit the torque to the wheels and get them mobilized.&nbsp; Torque is the force that produces the turning effect. Having said that, we can comprehend the role of a drive shaft as it is the driving force to move and maneuver the wheels.&nbsp; A drive shaft compensates for changes in length and angle because of deflection or manipulation to ensure outstanding synchronization between the shaft joints.&nbsp; Drive shafts are extensively used in different vehicles like marine drives, bikes, and locomotives; however, the function differs in different vehicles. The drive shaft configuration varies for different rides, such as front-engine rear-wheel drive, front-wheel drive, and four-wheel drive.&nbsp;
