Concluding Points
COST:
SHEAR FORCE:
NUMBER OF TRIANGLES
STEEP VS. SHORT TRIANGLES
CREDIT/BIBLIOGRAPHY
- The more costly structure was worth the money. The monetary difference between the first and the second bridge was $12,290. A large sum of money, but well worth the hit to the pocket book. In order to have a safe and overall complete structure for a bridge, well you know the old saying, you get what you pay for. The increased monetary cost for the improved bridge, was indubitably worth the extra cost in materials and construction.
- 283,790/296,080 = .9584. 1-.9584 = 0.0416. Thus the additional cost benefit is 4.16%
SHEAR FORCE:
- The first bridge failed after a shear force of 6.14 lbs was applied to the structure.
- The second bridge failed after a shear force of 10.20 lbs was applied.
NUMBER OF TRIANGLES
- The higher number of triangles within the bridge structure, the better off the structure will withstand the brute shear force.
STEEP VS. SHORT TRIANGLES
- The taller the triangles, the more shear force can be applied to the members around it before it breaks and fails, versus the shorter triangles which will easily snap much faster than a steeper structure.
