Question:
“I am confused on how to start. The data given to us is about the sensor and time.”
Answer:
Please look at Prof. Moon’s description of the lab. You’ll see in item #5 that you need to know the maximum strain. In order to calculate that maximum strain you need to look at it over time to see an “average” when there isn’t a truck and then find the maximum when there is a truck.
Hint:
If you plot the strain (individual or average) over time using Excel you’ll almost certainly see a negative peak as well as the average that will allow you to determine strain.
In the lab description we are given an example of how to calculate the cross-sectional area of the top chord. Are we supposed to know which member the measurements were taken at? The excel spreadsheet has "(ue)" next to every sensor's name. Does that have something to do with the location?
