SUMMARY

The discussion focuses on calculating the bending moment diagrams for a bridge that extends from 17.5 meters to 35 meters. Key parameters include a resting point load of 375 kN, a hydraulic pump load of 525 kN, and a bridge mass of 15 metric tons. To accurately analyze the bending moments during extension and at full length, additional information regarding support conditions and load distribution is necessary.

PREREQUISITES
  • Understanding of structural engineering principles
  • Familiarity with bending moment diagrams
  • Knowledge of load calculations in bridge design
  • Proficiency in using structural analysis software
NEXT STEPS
  • Research how to create bending moment diagrams for cantilever beams
  • Learn about the effects of point loads on beam deflection
  • Study the principles of static equilibrium in bridge structures
  • Explore software tools for structural analysis, such as SAP2000 or ANSYS
USEFUL FOR

Structural engineers, civil engineering students, and professionals involved in bridge design and analysis will benefit from this discussion.

The bridge is full extend 35 meters long, and retracted 17,5 meter long.
When the bridge is installed it rest on piont(375kN) and a
hydraulic pomp (525kN) , the mass of the bridge is 15 metric ton.

my question is how do I calculate the bending moment diagrams when it is extending and how do i calculate the bending when it is at 35 meters.

More information is needed before this problem can be analysed properly .

Is this a homework question ?
