Bridges are not classified as levers; rather, they are structures designed to span physical obstacles and support loads. Levers are simple machines that amplify force through a fulcrum, while bridges distribute weight and tension across their components to provide stability and support. However, both bridges and levers utilize principles of physics to manage forces, but they serve different functions and are constructed differently.

Whether a truss bridge is better than a cantilever bridge depends on specific project needs and site conditions. Truss bridges generally offer greater load distribution and can span longer distances with less material, making them efficient for heavy loads. However, cantilever bridges are often advantageous in areas where construction is challenging, as they require less support during assembly. Ultimately, the choice between the two depends on factors such as load requirements, environmental conditions, and budget constraints.

For a railway bridge with a height of 10 meters, a pile pier is often more economical due to its ability to transfer loads effectively into deeper, more stable soil layers, which can reduce the need for extensive excavation and material use. Additionally, using pre-cast concrete piles can speed up construction and lower labor costs. The choice ultimately depends on soil conditions and local material availability, but pile piers generally offer a cost-effective solution for such heights.

It was built in the late 19th century and is noted for its innovative engineering.

A suspension bridge exhibits a parabolic shape due to the way the cables distribute tension and load. When a load is applied, the weight of the bridge and any traffic creates a curve in the main cable, which ideally forms a parabolic arc. This shape minimizes the bending moments and forces acting on the towers and deck, allowing for efficient weight distribution. Additionally, the geometry of a parabola ensures that the vertical forces are evenly distributed along the span of the bridge.
