Deflection of a steeped shaft

  1. Sep 10, 2007 #1
    hello everyone.

    i want to know that can we treat stepped shaft as a beam while finding the deflection.
    if yes then how do we find the deflection of a stepped shaft made of cs1030 steel. its first half is 50 mm radius and is 2440 mm long while the second half is 35mm radius and 800mm long.
    thank you for your interest.

    Yes, but each section has a different moment of inertia because the cross-sectional areas are different. There will be a discontinuity at the location of the change in diameter.
