partially uniform load calcs
i've been searching for the deflection formulae for a partially uniform load on a simply supported beam. in the old lincoln book the sketch is 3c. i can't find it in roarks either. that is when it's not in the centre.
the reactions and bending moments are given in all the examples i've googled but no deflection. why is this? and can someone help me with the formulae if the beam is "l" long and the uniform load is "b" long and starts at "a" from r1.
thanks
you sure it's not in roark ? it's a standard problem.
in any case, can't you derive it from 1st principles ?
or maybe xcalcs.com has a ready made solution
@xcalcs ... look under beams, simply supported, distributed load
thanks for the leads, now got it.
if i did everything from first principles i'd be out of a job.
