Summarize the following:
If you want to make a bridge that can sustain large amounts of weight, you will need to use the best materials. As stated above, epoxy is the strongest bonding agent you can use. Also, you want to make sure you have plenty of pasta on-hand to make the necessary reinforcements to your bridge. Consider the benefits and disadvantages of various types of pasta.Rounded spaghetti noodles may be better for some parts of your bridge while flattened noodles, like linguine, may be better for other parts. The purpose of building a spaghetti bridge is to apply the theoretical principles of engineering to a real-life construction project. As such, how you design the bridge deeply impacts the overall strength of the bridge. Some tips for building a stronger bridge include:  Use triangular rather than rectangular trusses. Build the roadbed with multiple layers of pasta. You should leave the middle layer of your pasta roadbed unglued. Some flexibility in the pasta helps to redistribute weight across your bridge. The longer the gap a bridge has to span, the harder it will be to redistribute the weight from one area across the entire bridge. So, if it is up to you, making a shorter bridge will help your bridge sustain more weight. There is a relationship between the weight and strength of your bridge. Adding more pasta to your bridge during construction, when properly built, should add strength, but also adds more weight. The heavier your bridge is, the more likely it is that it will collapse when extra weight is applied. So, make sure you account for the weight of your bridge when designing your bridge.

Summary:
Select the best building materials. Design a stronger bridge. Limit the space your bridge must cover. Strike a balance.
