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

Click For Summary
SUMMARY

The discussion centers on the application of torque in analyzing tension in a beam supported by a wall. The pivot point is correctly identified at the junction where the beam meets the wall, which is essential for accurate torque calculations. The user confirms their understanding of the concept but seeks validation regarding the placement of the pivot point and the definition of the beam's edge. This indicates a solid grasp of basic mechanics principles related to static equilibrium.

PREREQUISITES
  • Understanding of basic mechanics principles, specifically static equilibrium.
  • Familiarity with torque calculations and their application in beam analysis.
  • Knowledge of pivot points and their significance in mechanical systems.
  • Concept of tension forces in structural elements.
NEXT STEPS
  • Research the principles of static equilibrium in mechanical systems.
  • Learn about torque calculations in more complex beam configurations.
  • Explore the effects of different pivot point placements on tension and torque.
  • Study real-world applications of beam tension analysis in engineering design.
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in structural analysis or beam mechanics will benefit from this discussion.

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 think I understand but just want to check if I did this correctly, or if there is more to it...

Where's the 'edge' of the beam ?

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.
