Passage V
A store sign is to be suspended from a 1-meter-long horizontal rod. The rod is supported by a cable at one end and a bracket at the other (see Figure 1).
The sign's weight, W; the angle, 
, between the cable and the rod; and the distance, d, between the centerline of the sign and the wall will each affect the tension, T, in the cable. The cable will break if T exceeds the cable's breaking force, F.
Table 1 lists F, in newtons (N), for stainless steel cable of various diameters. Figure 2 contains graphs of T (in N) versus for various W (in N), where d= 0.50 m. Figure 3 contains graphs of T versus for various d, where W=100N.
26. Consider the data in Figure 3 for d = 0.25 m and d= 0.50 m. For each value of d, what value of θ results in T= 100 N?
Your Answer is
Correct Answer is G
Explanation
Look at figure 2, when the vertical coordinate T=100, the horizontal coordinates of the two lines with d being 0.25 and 0.5 are 30 and 50 respectively
