Homework Help Overview
The discussion revolves around a static equilibrium problem, focusing on net force and torque conditions. Participants are exploring the implications of forces acting at a support point in a system.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- Participants discuss the necessity of drawing a free body diagram (FBD) and question the presence of horizontal force components at the support point. There are inquiries about whether these components are relevant to the problem's solution.
Discussion Status
The conversation is ongoing with various interpretations being explored. Some participants suggest that taking net torque around the support point could simplify the analysis, while others emphasize the need to consider horizontal forces and friction to maintain equilibrium.
Contextual Notes
There is mention of assumptions regarding sufficient friction at the support to prevent slipping, which is critical for the equilibrium condition being discussed.
Net Force = 0
Net Torque = 0

This is irrelevant to the solution of the problem, why do you think it is an issue?

You can do that if you want, but the question you should ask yourself once you have done that is: can I compute the result without knowing the answer to the question you just asked?

I know the message you want to give me .. I would take net torque around the support point so all forces from it will have 0 torque.
But i asked the question because there must be horizontal force produced from there. because there is only single horizontal force genrated from rope. so there must be a balancing force

Yes, you can assume there is sufficient friction at the support to prevent it slipping.Sarah00 said:

Just to add: Otherwise it will slip and not be in equilibrium.
