Hi and thank you for taking a look at my problem..(adsbygoogle = window.adsbygoogle || []).push({});

I'm very familiar with doing deflection calculations for beams of constant cross-section but I find myself needing to now do calculations on a beam of varying cross-section and I'm completely lost.

It's a relatively simple case in that the beam is a round/tubular, constant/symmetrical taper. It's supported in cantilever at the large end and the load is a single point load at the tip. I've attached a simple sketch if it helps.

As a starting point, is it even possible to derive an equation for the deflection of the beam or can this only be calculated by FEA? (excuse my ignorance!)

If anyone can offer any help/pointers/equations I would be very grateful.

Thanks for your time.

Simon
