# Equilibrium of a Non-concurrent force system

• hokage12368
In summary,You tried solving it but you don't know how to start because you think the given values are insufficient. You first tried to compute for individual forces of C, D, and F but you can't their values. You need to show us what you tried so we can see where you're getting stuck.

Homework Statement
The frame is supported in pivots at A and B. Compute the horizontal reaction at A and the horizontal and vertical components of the reaction at B. Neglect the weight of the beams
Relevant Equations
How to compute it? Do I need to get the value of individual forces before I get the value of A and B?

I try the moment of A and B but I don't know how to proceed after this or does my solution wrong?

Try considering the equilibrium of the horizontal rod first.

It is the same, after that I don't know how to proceed. May I know if the given values is sufficient to solve the problem? Maybe that's the problem why I can't solve it

Sorry, I as said before other than getting the equilibrium of A, B and C I don't know how to proceed anymore that's why other than what I posted here which is an incomplete solution, I don't have a complete solution. That's why I am asking for help on how to proceed or am I doing it right because I can't proceed any further.

Why all this fascination with detail, following forces through all the members ?
The particular structure shown weighs nothing and is perfectly rigid.
So step outside the box and replace the entire structure by one triangle, ABC.
Allow the problem to collapse, so you can see the solution in your head.
Or am I missing something ?

Welcome!
Did you get any progress?
Can you visualize the function of each pivot support?
The frame and the load can rotate around the vertical axis A-B.
How are the pivots A and B stopping it from sliding down or tilting over?
