SUMMARY

The force acting on the bridge crane is definitively 2820 N, derived from the downward forces of the beam's weight and the load it carries. The upward reaction forces from the supporting pillars counterbalance these downward forces. The discussion highlights a common error in interpreting the forces acting on the beam, emphasizing the importance of accurately reading the problem statement and diagram.

PREREQUISITES
  • Understanding of static equilibrium in structures
  • Knowledge of force diagrams and free-body diagrams
  • Familiarity with basic physics concepts such as weight and reaction forces
  • Experience with bridge crane mechanics
NEXT STEPS
  • Study static equilibrium principles in structural engineering
  • Learn to create and analyze free-body diagrams
  • Research the mechanics of bridge cranes and their load capacities
  • Explore common errors in force analysis and how to avoid them
USEFUL FOR

Engineers, physics students, and anyone involved in structural analysis or crane operation who seeks to understand the forces acting on bridge cranes and improve their problem-solving skills in mechanics.

My "working"
The answer is simply 2820 N

Your diagram is incorrect. We are looking at forces on the beam. These are its own weight and the weight from the load, both of which are downwards. The reaction forces from the pillars at each end are however upwards.
 
Ahhh I am grateful as I see the easily avoidable error I made by simply not using my brain properly and reading the question, thank you!
