A chain composed of four identical links is suspended by a rope and does not move. How many force vectors would be drawn on the free body diagram of each link and which direction would they point?

Answer 1

FIRST LINK (top): Upward force from rope (tension), downward normal force from link 2 (below), and downward force from earth (weight)

SECOND LINK: Upward normal force from link 1 (above), downward normal force from link 3 (below), and downward force from earth (weight)

THIRD LINK: Upward normal force from link 2 (above), downward normal force from link 4 (below), and downward force from earth (weight)

FOURTH LINK (bottom): Upward normal force from link 3 (above), downward force from earth (weight)

^ Is that right?

Also, I have to rank the magnitudes of all of the forces from largest to smallest, including how I used Newton's second and third laws.
