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.
24. According to Figure 3, if d = 0.75 m and W = 100 N, the greatest change in T occurs when θ increases from:
Your Answer is
Correct Answer is F
Explanation
Looking at the line of d=0.75 in figure 3, it is found that when the abscissa is between 10-20, the ordinate drops the fastest
