Your name
How Well Would Your Final Model perform in the following situations?
(1 means safety problems, 2 means potential bridge closure, 3 means possible collapse, 4 means no problem)
1
2
3
4
A snow storm that drops a foot of snow, and adds a 10% load to the weight of the bridge
A flood that increases the river height 4 meters
A crash that sends a vehicle tragically over the edge of the bridge
An extreme heat wave
Clear selection
Explain your rationale for each of the 4 choices you made above
County supervisors often pick the cheapest bridge design for an area.  Based on your work with this program, do you feel this is a good idea?   Why or why not?
List 3 members of your bridge.  For each, determine the  mass of the member, the member cost, and the type of material.  
Find which member has the greatest tension in Newtons, and list (Member #, Tension (N)
Find which member has the greatest compression in Newtons, and list (Member #, Tension (N)
Can a member have compression and tension simultaneously, according to your model?   Explain, using a specifc member number if applicable.
How do carbon steel, hollow tube, and quenched/tempered steel compare in strength?   Why not just build the bridge out of the strongest material?
