Hi All,
thanks for feed back. I am after a formula to find what force (F) the beam can withstand before plastic deformation and what force (F) caused it to bend by 4 mm.
It's a fully FIXRED beam fixed both ends, the difficulty for me is that its not a normal square beam it's a channel section.
Needing assistance to calc the force needed to bend channel shape beam by 4mm beam with fixed centre load across the two channelhttp://files.engineering.com/getfile.aspx?folder=9a3fd167-e3c4-4ed0-8051-5a3fdf9e7ee9&file=CHANNEL_BEAM_WITH_CENTRE_LOAD.png
