Hi all,
A uniform horizontal beam: RA to RB is 8m
CWM = (2x20)+(5x5)+(7x30)+(9×15) = ACWM 40 + 25 + 210 +135
Not taking the 1st term (1x15) = (6×20)+(3x5)+(1×30) .I am confused with how you jump to 6x20 (and so on) my logic is to ad the surplus 1 on the end to the first moment of 2 at RA add that to the second moment of 3 to get 6 and x that by 20?
Without being able to draw s diagram its hard to describe. I believe im on the right track...
