Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I have a shaft supported on both sides with a charge on each bearing, as shown on the following link: http://www.engineersedge.com/beam_bending/beam_bending4.htm

I need to calculate the shaft deflection with the formula provided on the website, but my shaft often have different section (ie Ø23 mm machined to Ø20 mm for the bearings). I am not too sure how to calculate a deflection since the Moment of Intertia will depend on the position.

Thank you very much for any help.
