A small boat hangs from two davits, one of which is shown in the figure. The tension in line ABAD is 82 lb, determine the moment about C of the resultant force exerted on the Davit.
Point A is at (0,7.75,3), B is directly below, at an un-given height, C is (0,0,0), D is (6,0,0). There are no coordinates for B from the figure. How do you find the resultant vector? How does Tension spread over the line ABAD?
