Questions
Are these problems that need to be done for the lab?
(2) Monitor the strain gage data under traffic and inform the engineer operating the data acquisition system when a truck approaches so they can record the strain time-history.
(3) Take a photograph of the truck that caused the measured strain in the top chord and note the lane (upstream, downstream or center) it occupied.
(8) Is the computed truck weight less than the legal limit? (Where are we to find the legal limit?)

And is the max stress level the values in the one in the -30 range or in the 4-5 in/in range
Response
#2 & #3 – We provided the strain gauge data and the truck photograph this time
#8 – As Dr. Moon said in his lecture and I said in class today you can find this by a Google Search looking for Federal truck weight load limit or something similar.
Max Stress Level – It’s up to you to determine the max stress level. Usually a maximum (in absolute terms) is the greatest departure from the average.
