Question 9 of 10 < -/ 15 VIEW T UITLICS Current Attempt in Progress The rigid square frame in the 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 7 of magnitude 442 N. For each of the following, give the number of the correct answer: (a) Is bar AC in tension or compression? (b) is bar AD in tension or compression? (c) Is bar BC in tension or compression? (d) Is bar BD in tension or compression? (e) Is bar CD in tension or compression? (f) What is the magnitude of the forces causing the tension in the bars which are in tension? (g) What is the magnitude of the forces causing the compression in the other bars? (Hint: Symmetry considerations can lead to considerable simplification in this problem.) G B 7 E (a) (b) (c)
