How do you design a bridge with these materials?

In summary, the conversation discusses building and designing a bridge with limited materials and the need for a thesis on the topic. The suggested approach is to consider the problems that need to be solved, such as the length of the span, weight to be supported, and the type of foundation. It is also suggested to think about triangles and the importance of an object's dimension in resisting bending.

how do you build & design a bridge with these materials?

4 drinking straws
10 pieces dressmaker's oin
5 pieces of 5-peso coins (the bridge should be able to withstand the weight of these coins)
1 short bond paper
and a
1 meter sticky tape


Anyone who has performed this project already? Please! I'm in dire need of help.

and by the way, i need a thesis regarding this! please! help me! :smile:

This appears to be schoolwork. Tell us your ideas and let us know where you are stuck.

To help you get started, remember that engineers are problem solvers. So first you determine the problems to be solved such as: the length of the bridge's span; weight to be supported, including the bridge's own weight; dealing with torgue on the structure (in large suspension bridges this is partly handled by the width of the structure and by placing a curve toward the end on one bank); type of foundation and location of foundation points. These are some of the possible problems to be considered.

Tell us your ideas so far.

Agreed. Moved.

Think "Triangles."

Also, an object with a longer dimension perpendicular to the direction of bending resists bending better than a "flatter" object.
 

1. How do you choose the best materials for a bridge design?

Choosing the best materials for a bridge design requires careful consideration of several factors, including the type of bridge, its location, and the expected load and stress it will experience. Engineers typically consider materials such as steel, concrete, and wood, and select the most appropriate based on their strength, durability, and cost.

2. What role do safety standards play in designing a bridge?

Safety standards play a crucial role in bridge design as they ensure that the structure can withstand expected loads and remain safe for public use. Engineers must comply with building codes and regulations set by governing bodies to ensure the bridge meets safety standards for its location and intended use.

3. How do you determine the size and shape of a bridge?

The size and shape of a bridge are determined by several factors, including the expected load, the span required, and the topography of the site. Engineers use mathematical calculations and computer simulations to determine the most efficient and structurally sound size and shape for the bridge.

4. Can you design a bridge with unconventional materials?

Yes, bridges can be designed with unconventional materials such as bamboo, plastic, or even ice. However, engineers must carefully consider the strength and durability of these materials and ensure they can withstand the expected loads and environmental conditions.

5. How do you ensure the longevity of a bridge design?

To ensure the longevity of a bridge design, engineers must consider the materials used, the expected load and stress, and the environmental conditions at the site. Regular maintenance and inspections are also essential to identify and address any potential issues before they become major problems.
