Calculating forces in pulley elevator system

Click For Summary
SUMMARY

The discussion focuses on calculating forces in a pulley elevator system, specifically the axial members, loading on lifting eyes, and the pulley shaft. Participants emphasize starting with the forces acting on the sheave and recommend writing equilibrium equations for the sheave axle G. This foundational approach is essential for accurately determining the forces involved in the system.

PREREQUISITES
  • Understanding of basic mechanics and statics
  • Familiarity with equilibrium equations
  • Knowledge of pulley systems and their components
  • Ability to analyze forces in structural systems
NEXT STEPS
  • Study the principles of static equilibrium in mechanical systems
  • Learn how to derive and apply equilibrium equations for pulley systems
  • Research the forces acting on sheaves and their implications in design
  • Explore case studies involving pulley systems in engineering applications
USEFUL FOR

Mechanical engineers, structural analysts, and students studying mechanics who are involved in the design and analysis of pulley systems.

I need to find the forces in the axial members, loading on the lifting eyes and pulley shaft.
Attached is a photo of the pulley system.

I have no idea where to start so any help would be muchly appreciated.

You start with the forces acting on the sheave. Write a set of equilibrium equations for the sheave axle G, and work back.
