cosine load distribution
cosine load distribution
(OP)
Hi,
I am deaing with a beam having a reaction moment in the middle of the beam. Beam is simply supported. Assumption is that the load have a cosine distribution with a running load w = (pi*2 x M)/L*2 x 2 [lb/in].
Does anybody know where can I find more information about cosine load distribution, confirming that formula?
Thank you in advance all,

RE: cosine load distribution
FWIW, i'd use a linear distribution to apply moment.
also you "cosine" definition is incomplete, you need the phase angle ... is the peak load at the middle (that sounds odd, but that's what i think of as a cosine dist'n, modelling the 1st and 4th quadrants) or is minimium load at the middle (sounds more realistic for a moment loading, but sounds more like a sine dist'n, modelling the 1st and 4th quadrants; of course exactly the same as cosine 1st and 2nd quadrants) ?
