Final answer:
The stone or concrete blocks that ground a suspension bridge are called anchorages or anchoring blocks, essential for distributing the tension from cables and maintaining the structural integrity of the bridge.
Step-by-step explanation:
The stone or concrete blocks that serve as the foundations for the towers that support a suspension bridge are commonly referred to as anchorages or anchoring blocks. These blocks are crucial to the stability and strength of suspension bridges, such as the iconic Golden Gate Bridge. The purpose of the anchorage is to bear the tension from the cables and distribute these forces safely into the ground, ensuring the structural integrity of the bridge.
Similar to the role of a keystone in an arch, which locks all other stones in place, anchorages must be incredibly strong to maintain the equilibrium of the suspension bridge. The weight of the bridge, along with any additional load it carries, is transmitted through the cables to the anchorages, necessitating their robust and heavy-duty construction.
