Dear all

I have been given task of to reduce the deflection of overhanging shaft.

shaft geometry is stepped one. If we increase the load acting diameter cross section immediately we can reduce the deflection but our constraint is we cannot change that one. So what I have done, I have changed the support diameter then the deflection got reduced.My querey is, in general beam deflection equation we are not at all input the support diameter cross section,then how makes the deflection got reduced ? I want to know the theoretical backround for the reduced beam deflection in my case.

Thanks for your reply
