Cable Tension vs. Tower Height
The twin cables would slope more steeply if the towers were taller. When the slope is steep, more of the tension (pulling) force in the cables is efficiently directed upward, rather than horizontally. But taller towers (the Bridge’s were the tallest in the world when built) mean more structural and construction problems and more cost a classic engineering tradeoff.
