How to Approach Pulley Problems Using Method of Members?

Click For Summary
SUMMARY

The discussion focuses on solving pulley problems using the Method of Members, specifically addressing a pulley with a radius of 2 feet. Key equations referenced include EFy=0, EFx=0, and EMc=0, which are essential for analyzing forces in static equilibrium. The final answer provided in the textbook is (5/8)W, indicating the relationship between the weight and the tension in the system. Participants clarify that the reaction at point C has both vertical and horizontal components, while the tension in the cord pinned on member AD only has a horizontal component directed to the left.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with the Method of Members in structural analysis
  • Knowledge of force decomposition into components
  • Basic concepts of pulleys and tension forces
NEXT STEPS
  • Study the Method of Members in-depth for structural analysis
  • Learn about force decomposition techniques in physics
  • Explore static equilibrium problems involving pulleys
  • Review examples of tension calculations in pulley systems
USEFUL FOR

Students in engineering mechanics, physics enthusiasts, and professionals involved in structural analysis or mechanical design who seek to enhance their understanding of pulley systems and the Method of Members.

Method of Members, With Pulley.

1. The radius of the pulley is 2ft.



2. Well, I don't know where to start. I know there are three equations EFy=0, EFx=0, EMc=0 but I don't know what the first member to consider and how to solve this type of problem. Especially a pulley is concerned! Please help.



3. The final answer given in the textbook is (5/8)W.. So far I'm thinking about the reaction at C. Does it has both vertical and horizontal component? And the tension cord pinned on member AD, is it only horizontal to left or does it also has a vertical component?

Thanks for those who will help!

Can somebody give me a hint on the pulley?
 
In general, the reaction at point C appears to have a horizontal and vertical component. The force of the cord on the pinned cord connection in member AD has only a horizontal component to the left.
