SUMMARY

The discussion centers on solving an Internal Indeterminate Truss problem, specifically focusing on the member AC. The user attempted to find the force in member AC by removing it and applying a virtual unit force, resulting in a calculated answer of 2.28. However, the expected answer is 1.62, leading to confusion and a request for assistance in identifying the error in their calculations. The user has verified their work multiple times but remains uncertain about the mistake.

PREREQUISITES
  • Understanding of static equilibrium in structures
  • Familiarity with truss analysis techniques
  • Knowledge of virtual work principles
  • Proficiency in solving equations related to internal forces in trusses
NEXT STEPS
  • Review the method of joints for truss analysis
  • Study the application of virtual work in structural analysis
  • Learn about redundancy in truss structures and how to address it
  • Practice solving similar Internal Indeterminate Truss problems
USEFUL FOR

Engineering students, structural analysts, and professionals involved in truss design and analysis will benefit from this discussion, particularly those working on internal force calculations in indeterminate structures.

Homework Statement


In this problem , it's a Internal Indeterminate truss .

Homework Equations

The Attempt at a Solution


So , I remove one of the redundant member , AC and solve the problem .
For the first part , I found the real force first . for the second part , I apply the virtual unit force at AC ...I gt my ans = 2.28 , but the ans given is 1.62 . I have checked thru my working many time s, yet I still can't find my mistake , can someone help please??
