The forces that acts on the bridge is the way the bridge is built or the mass that is put on the bridge. Some are different it only depends on how the bridge is built.
Tension and compression are the two forces that act upon a bridge.
The Tower Bridge of London is primarily subjected to three main forces: compression, tension, and shear. Compression forces act downwards on the bridge, pushing the structure together. Tension forces act upwards, pulling the structure apart. Shear forces act parallel to the surface, causing different parts of the bridge to slide past each other. These forces must be carefully considered in the design and maintenance of the bridge to ensure its structural integrity.
A cable stay bridge may transfer forces that act on it by eventually transfer into a bedrock beneath the bridge foundation. One way of determining how this done is by using the seesaw method.
In cantilever bridges, the main forces that act on the structure are tension and compression. Tension forces occur in the upper portions of the bridge where the material is being pulled apart, while compression forces occur in the lower portions where the material is being pushed together. These forces work together to support the load of the bridge and transfer it to the foundations.
There are many forces acting on a truss bridge compression, tension, and torsion. The truss bridge uses equilateral triangles to spread out the stress of the load on these forces along the hold structure.
For a start, it's unavoidable that gravity acts on the bridge. Next, if the bridge is not to fall through to the center of the Earth, Earth must push up on the bridge. There may also be forces caused by wind.
The arch bridge spreads load (the weight of the bridge and the traffic on it) from the deck to the abutments (the supports at each end) and into the ground. This creates a lot of compressions.

When a bridge twists due to wind or uneven loads, it experiences torsional forces that create shear stress in the materials. These forces can lead to bending moments, resulting in flexural stress across the bridge's structural members. Additionally, the uneven distribution of loads can induce axial forces, which can either compress or tension the materials, further impacting the bridge's stability and integrity. Overall, these forces must be carefully analyzed in the design to ensure the bridge can withstand such conditions.
Depends on the type of bridge. Suspension bridges, for example, have tension holding them up. All are acted upon by gravity, and to a lesser extent, the force of contact with the wind.
Some Forces do not involve physical contact between the bodies on which they act. -Jauan Williams 3182163642
Some forces that can act upon a moving object include friction, air resistance, gravity, and applied forces like pushing or pulling. These forces can affect the speed, direction, and motion of the object.
