Hi,
When looking at a photo or sketch, I find it hard to take out the important bits and turn it into a freebody diagram. I am doing this question (pic attached).
Im quite unsure how to even begin. I've though of a few ways to start analysing it.
The first way analyses AD as a whole. And essentially all the forces would produce a moment about C.
the bottom pic shows the forces (the ball exerts 800N) and I would calculate the reactions in the supports. I would be tempted to find the reactions then put them back into the analysis mentioned above (moments about C). The only prob is, I am not sure its as easy as saying ƩF(y)=0. ∴Reaction(D) = Reaction(E) = -400N.
Are there any pointers? I do have the solutions manual however Id just like a nudge in the right direction before taking a peek. Thanks.
