How will I calculate the forces involved in a truss and suspension bridge, my teacher did not explain this fully and I'm confused as hell.

The answers are correct (to 2sf) for the shape as it is drawn. I get 30.05 for the force in the leftmost blue truss.
Truss bridges are made of interconnected triangles that distribute weight and tension evenly, while suspension bridges use cables to support the weight of the bridge and transfer it to anchor points.
Truss bridges are typically made of steel, while suspension bridges can be made of steel, concrete, or a combination of both. Some modern suspension bridges also use carbon fiber materials.
Engineers consider factors such as the length of the bridge, the expected weight and traffic load, and the environmental conditions of the site when determining the design and dimensions of a truss or suspension bridge.
Truss bridges are generally cost-effective and easy to maintain, but may not be suitable for longer spans. Suspension bridges can span longer distances and are aesthetically pleasing, but may be more expensive to build and maintain.
Both truss and suspension bridges are designed to withstand natural disasters such as earthquakes and high winds. They are built with sturdy materials and structural components that can withstand these forces and remain standing.
