Free-body diagrams for each of the four links can be presented in the diagram below.
A chain is suspended by a rope as shown at right. The chain is composed of four identical links and does not move.
A. In the spaces below, draw a free-body diagram for each of the four links. Label each of the forces as you were instructed in the tutorial Forces.
B. Identify all the Newton's third law (action-reaction) force pairs in your diagrams by placing one or more small "X" symbols through each member of the pair (i.e., mark each member of the first pair as , each member of the second pair as , etc.).
C. Rank, from largest to smallest, the magnitudes of all the forces on your diagrams. Explain your reasoning, including how you used Newton's second and third laws.
