Answers are right I got 5/5 tyyyy
Well, if you're building a bridge, you don't want it sagging in the middle like a tired hippo. So, the best way to build the bridge would be to link two or more beams end-to-end to keep it nice and straight. Straight bridges are all the rage these days, you know. Just make sure to support those beams properly, or the whole thing might turn into a comedy sketch. Nobody wants to witness a bridge collapsing, trust me.
The best way to build a beam bridge that spans 500 feet (152 meters) is to:
- Drape steel cables over the supports of the beam bridge to hold up the roadway.
By draping steel cables over the supports, the bridge will be able to distribute the weight evenly and provide adequate support for the roadway. This method helps prevent the bridge from sagging in the middle and ensures stability and durability.
The best way to build a beam bridge that spans 500 feet (152 meters) is to drape steel cables over the supports of the beam bridge to hold up the roadway.
To understand why this is the best way, we need to consider the forces acting on a bridge. When a bridge spans a long distance, it experiences a significant amount of weight and the force of gravity acting on it. This weight can cause the bridge to sag in the middle if it is not properly supported.
By draping steel cables over the supports of the beam bridge, the weight and force of gravity are transferred from the beams to the cables. The cables are then suspended from the supports, which helps to distribute the weight evenly and prevents the beam bridge from sagging in the middle.
This method of using steel cables to support a bridge is commonly referred to as cable-stayed bridge construction. It is a popular choice for long-span bridges because it provides excellent structural stability and can be more cost-effective compared to other methods like suspension bridges.
So, in summary, when building a beam bridge that spans 500 feet (152 meters), the best way is to drape steel cables over the supports of the bridge to hold up the roadway and distribute the weight evenly.
