The 1,432-foot-long Leonard P. Zakim Bunker Hill Memorial Bridge in Boston is the world's widest cable-stayed bridge (183 feet wide, carrying 10 lanes of traffic). The bridge has 116 cables. Assume that the bridge weighs approximately 5000 tons which is divided evenly among all the cables. (Recall that the weight of an object is a force in the vertical direction.) Give the Cartesian vector equation for the force carried in the longest cable which forms the hypotenuse of a 3-4-5 right triangle. Cable (5) Tower (3) Road (4)
