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...
