Thread: nonuniform distributed loads question

Hello,

Attached are questions I am having trouble coming up with the point loads. My book does not explain it well enough, to let me figure it out.

Can someone help me with the formula to solve these. I have tried a few things and nothing is coming close to the answers.
The problems I am inquiring about is.
55, 60 61.

I can figure out distributed loads, but when they are non uniform, Again my books does not explain it well enough.
If someone can help me with this, it would be greatly appreciated, thanks.

For 61 for instance. Do I take 3kN X4 then divide by 2. Then place that value at 1/3 of 4m??
OR do you take 3kN and X by the entire thing 12m and place that value at 1m. THEN difference of 7 and 3 is 4X6 all divided by 2 for the force. Then place that value at 1/3 of 6, plus the 4m at the beginning when taking the moment from A.
Does that make sense. the last one would be the difference still of 4 X 2, which is 8 at the 11m mark??

Can someone help me please, thanks for any help.
