Explanation / Answer

(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
