I have already solved my problem and would have marked it solved if i knew how. Your answer was the one I was looking for, thank you for taking the time to read the problem and reply.
Yes that was me. I know the method to calculate a solution providing I know which directions the horizontal reaction forces act.
My question was how do I know which direction the reaction forces act or what bit of information in that diagram tells me that HA and HF both act to the Right.
Homework Statement
I am to find the reactions of a 3 pin frame.
Homework EquationsThe Attempt at a Solution
So how do I know which direction to label the horizontal reactions? In the diagram HA and HF are in the same direction, I was under the impression that reactions are opposite to applied...
