    - Axle is a supporting element which is non-rotating and supports rotating elements such as wheels, pulleys, etc

    - Axles do not transmit torque but are subjected to bending moment or axial force.

    - Front axle of car and wheel axle of motorcycle are the examples of axles.

    Shaft: It is a rotating element. Shafts transmit torque and are also used to support gears, pulleys, sprockets, etc.

    - Different types of shafts are as follows:

    - Line shafts and counter shafts are transmission shafts. These transmission shafts are subjected to torque, bending moment and axial force.

    - Spindle and crankshafts are machine shafts. These shafts are also subjected to torque, bending and axial force
