Magnitude of Cable Tensions and Compressive Force

Click For Summary

Homework Help Overview

The discussion revolves around determining the magnitude of cable tensions and compressive forces in a mechanical system, as illustrated in a provided diagram. The subject area includes concepts from statics and force analysis.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to calculate the compression and tension forces using trigonometric relationships but expresses uncertainty about their correctness. Other participants question the directions of various reaction forces at point C and suggest considering the physical implications of those forces.

Discussion Status

The discussion is active, with participants exploring different aspects of the problem. Some guidance has been offered regarding the physical reasoning behind the forces, but no consensus has been reached on the calculations or interpretations.

Contextual Notes

The original poster indicates uncertainty about the equations used and the setup of the problem, which may affect the analysis. There is also a mention of a diagram that is not visible in the text, potentially limiting the context for some participants.

Homework Statement

There's a diagram with a rough free body diagram implemented.


Homework Equations



This is what I'm really unsure about.


The Attempt at a Solution



Finding Compression at BC: mg*sin(60) = 8495N
Tension AC = mg*cos(25) = 8890N

Not sure if that's right, but, it's all I can come up with!

Please help!

At point C, what is the direction of:

1. The reaction force of the beam?
2. The reaction force of the upper part of the cable?
3. The force applied by the lower part of the cable?
 
How do I find them?
 
Each of those has only two possibilities. Consider both, choose one that makes physical sense.
