Carbon Fiber Drive Shaft vs. Steel Drive Shaft!

We have steel as the worldwide material, used in many engineering application because its strength. But, how if we compare the steel with fiber carbon in strength (torsional stress)? What do you think, which one is the winner??? We all know that drive shaft is a mechanical component for transmitting torque and rotation so, it is used to connect other components of a drive train that cannot be connected directly. The drive shaft must be straight, strong, and durable. Watch the video below – a test of a carbon fiber drive shaft vs. steel drive shaft! They are twisted with force until they break… The stronger…???
