Hey Guys,(adsbygoogle = window.adsbygoogle || []).push({});

My question involves finding all of the forces acting upon each member. It is known that each side of the triangle has a length of l. It is also known that the force is acting at the very top of the triangle in the x direction (to the right) labelled as F.

Attempt:

I found moments at both supports (bottom left + bottom right) to be (½)F. I have found that AD = F and for some reason AB = 0???

Is this incorrect?
