Equilibrium normal reaction force problem

Click For Summary

Homework Help Overview

The discussion revolves around a problem related to equilibrium and normal reaction forces, as indicated by the reference to a free body diagram (FBD) and the forces acting on a ball. Participants are attempting to analyze the forces involved and their relationships.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to set up equations based on their FBD but encounters conflicting results for tension (T). Some participants suggest focusing on the normal reaction force as a key aspect of the problem, while others emphasize the need to identify all forces acting on the ball.

Discussion Status

The discussion is ongoing, with participants providing hints and suggestions for approaching the problem. There is an acknowledgment of potential misunderstandings regarding the forces involved, and some guidance has been offered regarding the importance of balancing forces.

Contextual Notes

Participants note that the problem specifically asks about the normal reaction force, which may influence the approach to solving it. There is also a mention of the need to consider multiple forces acting on the ball, indicating that the original poster may have overlooked some elements in their analysis.

The Attempt at a Solution


This should be easy, but I'm tired and just can't do it. If anyone can point me in the right direction that'd be great. I tried making a FBD, and had the equations:
[tex]Tsin30^{\circ} - 752N = 0[/tex]
[tex]344N - Tcos30^{\circ} = 0[/tex]

But, that then gives me two different answers for T. So I'm lost.

note: the question asks you about the normal reaction force, doesn't that give u a hint?
 
Is the answer 752N?
 
first identify all forces acting on the ball, draw a force diagram and then balance them.
there should be 4 different forces acting on the ball
 
Haha, well that means I got the question wrong. Damn.

[tex]Tsin30^{\circ} - 752N = 0[/tex]
[tex]344N - Tcos30^{\circ} = 0[/tex]
