If you have a beam with a force q evenly distributed on top of it, would this
ƩMA= 0 B*3,3-Cy*5,5-q*4,3*2,15=0
or this
ƩMA=0 B*3,3-Cy*5,5-q*4,3*2,15*3,35=0
be the right way to set up the moment point calculations? Basically what I'm unsure of is if I must incorporate the distance from q to the moment point in A and if so to use the entire distance q is working on+the distance from the beginning of q to point A, or to use the distance from the median of q to point A...
Hastily drawn up figure in order to illustrate what I mean:
