At the support point

, is there a horizontal force component?​

At the support point

, is there a horizontal force component?​

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.

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.
