Question 1:
Where can we find the dimensional data to calculate the cross sectional area for the bride? We looked through the Tacony Palmyra drawing saved in the 'resources' folder and did not see it. We saw some things that look sort of correct but it is a bit ambiguous which to use.
Response:
This is determined by the location of the member on the bridge. It’s why you need to know where you were. See the other blog posts.
Question 2:
It seems to me that the average of the sensor data is the best to use because it will have the least variation, however my friend thinks that the top member is the best because it has the direct tension forces from the truck. Does it matter which sensors we use?
Response:
Both of you are right. You can use either without problem. Each provides advantages. You might discuss them in the “sources of error” question.
