The rigid square frame in Figure consists of the four side bars AB, BC, CD, and DA plus two diagonal bars AC and BD, which pass each other freely at E. By means of the turnbuckle G, bar AB is put under tension, as if its ends were subject to horizontal, outward forces T of magnitude 535 N.

(a) Which of the other bars are in tension? What are the magnitudes of?

(b) The forces causing the tension in those bars and

(c) The forces causing compression in the otherbars?
