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

I am have slight problems with this problem. If I were able to use rectangular components, I'd be able to do it easily, but my professor was specific in that he wanted us to reach the solution using graphical methods.

The problem is:

"Two structural members A and B are bolted to a bracket as shown. Knowing that both members are in compression and that the force is 10 kN in member A and 15 kN in member B, determine the magnitude and direction of the resultant of the forces applied to the bracket by members A and B.

A rough sketch of the original diagram:

And my attempt at making the diagram using the triangle rule.

If my 2nd diagram is correct, how would I go about solving for the resultant force?

Thanks!
