Hey I'm just going over a past paper and I've lost the section of my notes RE this topic.

I understand how to draw the free body diagram when there is a pin involved, but not when it is connected at 4 points, the fact that they're at an angle is not helping.

Any help greatly appreciated, thanks in advance.
