Tension in Rope using Torque? Did I do this correctly?

Click For Summary

Homework Help Overview

The discussion revolves around the application of torque in analyzing tension in a rope connected to a beam. Participants are exploring the setup and assumptions related to the problem.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to validate their understanding of the problem by checking their setup and reasoning regarding the pivot point. Some participants question the location of the 'edge' of the beam, indicating a need for clarity on the physical setup.

Discussion Status

The discussion is ongoing, with some participants providing affirmations of the original poster's approach. However, there are still questions regarding the specifics of the beam's edge, suggesting that further clarification may be needed.

Contextual Notes

There appears to be ambiguity regarding the physical configuration of the beam and the wall, which may affect the analysis of torque and tension.

Homework Statement
A wooden beam is suspended as shown below. The beam has a mass of 25 kg and has a length as shown. A sign is of mass 10 kg is to suspended from the beam at a distance of 2/3 from the edge of the beam. What is the tension in the rope?
Relevant Equations
Torque = |F||d|sin angle or r x F

I set the pivot point to be where the beam meets the wall, the block on the left is the wall.
 
Your answer is fine.
