Statics problem, suport reactions and pins, IDK where to go

Click For Summary
SUMMARY

The discussion focuses on solving a statics problem involving a compound beam with forces of 12 kN, 48 kN, and 36 kN applied at distances of 1 m, 5 m, and 9.5 m from point A. The objective is to determine the support reactions at the fixed support A and the rockers at B and C, as well as the forces at pins D and E. Participants suggest using momentum and vertical force equations to isolate unknowns and simplify the problem-solving process.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with force and moment equations
  • Knowledge of compound beam structures
  • Ability to apply pin connection analysis
NEXT STEPS
  • Study the application of equilibrium equations in statics problems
  • Learn about the analysis of compound beams and their support reactions
  • Explore methods for isolating forces in multi-member structures
  • Review examples of momentum equations in engineering mechanics
USEFUL FOR

Engineering students, particularly those studying statics and structural analysis, as well as professionals involved in mechanical and civil engineering design.

Homework Statement
Determine the support reactions at the fixed support at A and the rockers at B and C for the compound beam shown. The beam consists of three members that are pin connected at D and E. Determine the forces at both pins D and E.
Relevant Equations
Everything is at equilibrium: equilibrium equations.
So far I got the simplified forces of 12, 48 and 36 kN, at 1, 5 and 9.5m (from A) respectively, but I'm confused as what to do next, can you help me?

You can write down a momentum equation and a vertical force equation for each of the mombers. One of these equations will only involve one unknown force or momentum. Solve that and one of the other equations will become easy.

Why 9.5 meters from A?
