Given that the engine hanging on the frame shown weighs 5 kN and the force in link CD is 12.5 kN tensile.
Use the right FBD to find the internal forces at point E: $N_e$, $V_e$, $M_e$
a) $N_e$ = 10 kN, $V_e$ = 2.5 kN, $M_e$ = -2.5 kN-m CCW causing T on top
b) $N_e$ = 10 kN, $V_e$ = 2.5 kN, $M_e$ = +2.5 kN-m CW causing T on bottom
c) $N_e$ = 0, $V_e$ = 2.5 kN, $M_e$ = +2.5 kN-m CW causing T on bottom
d) $N_e$ = 0, $V_e$ = 2.5 kN, $M_e$ = -2.5 kN-m CCW causing T on top
