(A)
lnternal normal force at point,
NC = 0 (net force in x direction = 0)
(B)
From equilibrium of moment about B,
-14*Ay + 8*F1 - 8*F3 = 0
-14*Ay + 8*544 - 8*263 = 0
Ay = 160.57 lb
from equilibrium of forces along y axis,
160.57 + Vc - 544 = 0
Vc = 383.42 lb
(C)
Net moment about C = 0
-10*Ay + 4*F1 - Mc = 0
-10*160.57 + 4*544 - Mc
Mc = 570.28 lb.ft
(D)
lnternal normal force at point,
ND = 0
(E)
VD = F3 = 263 lb
(F)
Net moment about point D = 0
-2*F3 + MD = 0
MD = 2*263
MD = 526 lb.ft
