For beams with ultra small width, the beam will bend laterally as i observed in my experiment. I have the SEM photo of this phenomenon and if you need, I can send it to you. > >Hi all, > > I have one small doubt.

In a normal beam with width very large in comparison to thickness, we expect beam to bend verticaly up/down. > > Now, if I make width small in comparison to thickness, will the beam bend laterally? >
