Question:

Fig. 3.32 depicts a decorative window (the thick inner square) weighing 100 N suspended in a patio opening (the thin outer square). The upper two corner cables are each at and the left one exerts a force (F1) of 100 N on the window.

(a) How does the magnitude of the force exerted by the upper right cable (F2) compare to that exerted by the upper left cable: (1) F2 > F1, (2) F2 = F1, or F2 (b) Use your result from part (a) to help deter-mine the force exerted by the bottom cable (F3).
