Static Equilibrium Homework: Net Force and Torque Solutions

AI Thread Summary
The discussion revolves around solving a static equilibrium problem involving net force and torque. Participants emphasize the importance of considering horizontal forces at the support point, questioning whether a horizontal force component exists. It is suggested that drawing a Free Body Diagram (FBD) can aid in visualizing the forces, although some argue that it's not essential for finding the solution. The necessity of sufficient friction at the support to maintain equilibrium is also highlighted, as insufficient friction would cause slipping. Overall, the conversation focuses on understanding the balance of forces and torques in static equilibrium scenarios.

This is irrelevant to the solution of the problem, why do you think it is an issue?
 
shuoldn't I draw FBD first?

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.

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