Final answer:
Cable-stayed bridges mainly rely on towers to distribute the load and do not require large anchorages nor two towers, as opposed to suspension bridges which require massive cables, anchorages, and typically two towers to distribute the loads.
Step-by-step explanation:
Cable-stayed bridges differ from suspension bridges in several key ways. Unlike suspension bridges, cable-stayed bridges do not require large anchorages nor do they need two towers. In a cable-stayed bridge, the cables are directly connected to the towers, which bear almost all of the load. This design allows for the cables to be attached to the towers at various points, spreading out the load among many cables and allowing for a relatively lighter structure compared to the massive cables and anchorages needed for a suspension bridge like the Golden Gate Bridge.
In a suspension bridge, the main cables that run between towers are anchored at each end and pass over the towers, where they hold up the deck by vertical suspender cables or rods. The weight of the bridge and the weight of the traffic is distributed along the length of the cables, giving them a characteristic curved shape known as a catenary. The large anchorages are necessary to counterbalance the tensions in the cables, while the two towers provide points for the main cables to pass over.
