14. Bar ABCDE is supported by three properly aligned journal bearings at B, C, and D as shown. The bearings do not exert thrust. The force vector at E is $F_E = \{100i - 200j - 150k\} lbs$. Select the correct equation for summing moments (in lb·ft) about the x-axis. Unknown support reactions are assumed to be in the positive direction.
a) $8C_x + 14D_y - 6D_z + 1400 + 900 = 0$
b) $2B_y - 6C_y - 5D_x - 800 - 1200 = 0$
c) $-8C_y + 5D_z + 2800 - 1200 = 0$
d) $-8C_y - 14D_y + 5D_z + 1600 = 0$
e) None of the above.
