Choose the correct answer
A
axial force in rafter
B
shear force in rafter
C
deflection of rafter
D
bending moment in rafter
Correct Answer
D. bending moment in rafter
Why is this the answer?
Loading the truss only at nodes keeps members in pure axial force; loads between nodes would cause bending in the rafter.
