Currently I am doing a straw building project with a group and we are in need of an interview from a real life engineer. So if anyone can help me with my design on our Girder Bridge then it would be appreciated.
The purpose of a straw bridge building project is to design, construct, and test a bridge made entirely out of straws. This project helps to develop critical thinking, problem-solving, and engineering skills.
The main material needed for a straw bridge building project is straws. Other materials that may be useful include tape, scissors, rulers, and weights. It is up to the individual to decide which materials to use for their specific project.
To design a strong straw bridge, it is important to consider factors such as the weight of the bridge, the span of the bridge, and the shape of the bridge. Triangular shapes are often the strongest for straw bridges. Additionally, reinforcing the joints with tape or additional straws can increase the strength of the bridge.
To test the strength of a straw bridge, you can add weights to the bridge until it collapses. It is important to record the weight at which the bridge collapses and to repeat the test multiple times to ensure accurate results. You can also test the bridge by seeing how much weight it can hold before it starts to deform.
Some common challenges when building a straw bridge include achieving stability, finding the right balance between weight and strength, and connecting the straws securely. Additionally, it can be difficult to create a design that is both aesthetically pleasing and functional.
