What example can be used for torsion?

An example of torsion can be seen in a twisted rope or cable. When one end of the rope is twisted while the other end remains fixed, it experiences torsional stress, which can lead to twisting and eventually failure if the torque exceeds the material's limits. Another example is found in mechanical systems, such as drive shafts in vehicles, where torsion is essential for transmitting power from the engine to the wheels.
