The bridge designers would test the materials to see which is strongest and to see which one can withhold the most damage. They also do their research to find the types of materials that are like that.

If it's more thick then it's ,mreo

Question 2: I think the thickness of the bridge does not matte as long as it is stable and is made of a strong material. Also if the the bridge is thicker then it adds more weight and can make the bridge collapse.

Q1. they can figure it out by testing it and doing the scale modal

# data[].attributes.body
The thickness of a beam is related to its strength because the more thick the beam is the more strength it can hold and withstand.

Question 1:
Bridge designers figure out what materials to use when building by testing each material under a weight and build a scale model of a bridge and test that to see what materials would work best.

# data[].attributes.body
They would need to know what materials are strong enough and will support a lot of weight because if you use weak materials to make a bridge or something that won't support even a car then the bridge won't be stable and could be dangerous.

# data[].attributes.body
I agree with your answer to question one. They tested to see which one would work

# data[].attributes.body
They run the materials through certain tests to see if the material with hold the weight they hope to put on it.

# data[].attributes.body
The thickness can also help with the balance

# data[].attributes.body
No, because the width does not matter. It is how strong it was or what materials the beam was made out of

# data[].attributes.body
If a beam is very thick it obviously means that more material was used. With more material being used it makes it heavier and stronger.

Question #2

# data[].attributes.body
It matters that materials are sturdy and built for it intended purpose. The designer had to also get his/her design approved by a engineer.

# data[].attributes.body
the bigger/thicker a structure is the more likely it is to collapse under it's own weight. To avoid this we can use things like triangles that are very strong and a low in mass.

No, the thickness of a bean is not related to the strength of a bean because the thickness is just how many layers it has. The strength is how good the bean is at holding up heavier objects until it SPLATS!

# data[].attributes.body
A bean needs to be thick enough to support the bridge. Why? Well, a bridge is very heavy and it needs some way of support! So, a bean would have to be thick enough to hold up the weight of the bridge. Alecxa Estrada

Bridge designers know what materials to use because they make tests before they build the actual bridge. They also would recreate the type of area that the bridge will be standing in so that way there is no potential errors when building the actual bridge.

# data[].attributes.body
They know because they have done it before. They have also learned through history and time what materials work best in order to accomplish there goal. When they go to school for there degree in architecture that is part of what they are taught or what they want to learn.

Question #1

# data[].attributes.body
I think the thickness of a beam really adds to the strength. I say this because When something is thick it will be harder to break.

# data[].attributes.body
The thickness of the structure matters because it has to be balanced in order to stay up.

I think they draw designs and do math equations to see if it can hold cars or other heavy objects

Bridge designers would first have to test out the materials. Whichever material is the best at supporting weight and is perfect for a bridge, then they know which material to choose -Alecxa Estrada

# data[].attributes.body
They would run certain materials through certain tests to test its strength,durability, and to see if either of the materials are stronger then the other.

# data[].attributes.body
I think they know which materials and designs will give the bridge the strength it needs because they have done reasearch on what can hold what and how it can help.

Dominick Wilson : I believe that they weigh the objects so that they know if it can withstand it

How do you think the thickness of a bean is related to its strength? Do you think the relationship is linear?

# data[].attributes.body
How do you suppose bridge designers know which materials and designs will give a bridge the strength it needs?
