Week 1 Challenge
1.
Aim - To find the more efficient type of truss in carrying gravity load between the two through type of truss as shown in the question.
Observation-
- It can be seen that both the trusses are pratt (Truss A)and howe type (Truss B) of truss.
- It can be seen in the attached figures,While carrying gravity load, In Truss A, the diagonal members(longer member) will be experiencing axial tension but in the case of Truss B, the diagonal members will be experiencing axial compression.
- And the vertical members will be experiencing axial compression force in truss A and axial tension force in Truss B.
- It is understood that, If a longer member carries compression then the chances of buckling is more.
Conclusion:
- So as in the case of Truss B, the diagonal member is experiencing axial compression, it is least efficient as compared to the Truss A in carrying gravity loads.
- So pratt type truss is most efficient in carrying gravity loads.
