You should consider the gravity of earth and the mass of the bridge because mass effects the gravitational pull on an object. Also, consider forces of nature. Consider the location of the bridge and how much trafficking will happen on it. If one of these are ignored your bridge could easily fall apart.
I think that one of the most important jobs for building the bridge would be the designing og the bridge and the engineering components that go along with designing such projects.

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.
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.
The main forces that affect bridges are gravitational forces (weight of the bridge and loads on it), tension forces (pulling forces on the bridge elements), compression forces (pushing forces on the bridge elements), and lateral forces (such as wind or earthquakes). These forces can cause stress, deflection, or deformation in the bridge structure, potentially leading to structural failure if not properly managed.
1.What are the different factors being considered in equipment designing?
external forces and internal forces
An engineer takes responsibility for designing the bridges but there are many more experts that are needed to build the bridge.
The three different places on a bridge that would experience different forces are the supports (where vertical forces are highest), the center span (where compression and tension forces are highest), and the connections between bridge sections (where shear forces are highest).
In bridge construction dead load, live load, and dynamic load must be considered. Dead load is the weight of the bridge itself. Live load is the moving weight on the bridge. Dynamic load comes from outside forces like wind and vibrations.

Their budget limit. And keep in mind the needs of the group of people they are building for.
