In the Bow notation system for graphical truss analysis (force polygons):
Choose the correct answer
Forces are labeled only at joints
Spaces between forces in the space diagram are labeled with capital letters; member forces are identified by the two letters on either side of the member; the force polygon (Maxwell diagram) is drawn using these letter pairs
Only reaction forces are labeled
Members are numbered not lettered
Correct Answer
B. Spaces between forces in the space diagram are labeled with capital letters; member forces are identified by the two letters on either side of the member; the force polygon (Maxwell diagram) is drawn using these letter pairs

Bow notation: capital letters assigned to each space between external forces and inside each panel of the truss (in the space diagram). Each member is identified by two letters (the spaces on each side). In the force polygon (Cremona/Maxwell diagram), vectors are drawn using the same letters. This enables systematic graphical solution of all member forces.
