Im trying to draw an FBD for this, but I don't know how the treat the distributed load or what forces the thing at E contributes. Is it some kind of support?
For the distributed load, I don't know what part of it the 800N/m and 400N/m refers to.
And for this question, I just don't understand anything that's going on in that diagram; is the position of the bar fixed? Is the platform fixed?
