A hinge at a wall and a cable support a uniform horizontal beam that weighs 1000 N. Four different arrangements of the cable are shown in the figure (a-d). In arrangement c, the cable is vertical. Rank the tension in the cable from greatest to least and answer the questions using the drop-down lists:

Greatest cable tension:

Second greatest tension:

Third greatest tension:

Least tension:

What is the magnitude of the tension force for arrangement c?

If the cable can take up to 750 N of tension before breaking, how many of the arrangements would still be intact (where the cable does not snap)?
