SUMMARY
The discussion centers on determining the correct answer for a 4-bit magnitude comparator homework problem. The participant concludes that options (A) and (C) are incorrect, and suggests that option (E) is the correct answer based on the analysis of the inputs. The reasoning includes the observation that when input A is 1, the output is true, and that the input at Y is at least twice that of the input at X, indicating a left shift. The only exception noted is when all inputs are zero.

As far as I can guess from the figure, the input at Y is at least twice that of the input at X (left shift). Thus F is TRUE.

TL;DR: This determine the support reactions at A & B
I tried calculate moment about a which is 2a(By + Bx + Ey + Ex +F) + a (Gy + Gx + Cy + Cx). But I don't think I'm correct, any help would be appreciated, this was a question on a final exam paper in my Mechanics course.
