Lab-3 – Bridge Collision – Grader’s Comments

• Specifically state "this was an implication of the lab" or "this was a limitation of the lab" in your memos. 
• Many used the height of the wall =8' instead of the length of the bridge =520' for question 4 when calculating the bending moment.  You needed to use the bridge length instead of wall height for Q4.  This changes your bending moment.  Partial credit was given for this question.
• Please put your first and last name in the title when you save the document.
• Be sure to follow the formatting instructions already in the lab: "Example of making formulas visible - We want you to display the formula for calculating the momentum. We show each of the ingredients. Then we show the formula - highlighted in pink. Then we actually calculate the result. Note that we used named variables to make the actual cells read readily."
• Part of being an engineer involves professional calculations and writing.  Your calculations may need to be checked by other engineers at a later date and thus you should be neat and organized.  If you are completing the labs via hand calculations, please be neat and organized. 
• Instead of only stating what numbers were obtained during the calculations, try to think if the numbers make sense and why.
• If you are scanning in calculations, please combine them into a single PDF.
