Main Question or Discussion Point
when a particle is constraint to move on a circle, what are the constraint forces
What is the particle?when a particle is constraint to move on a circle, what are the constraint forces
usljoo, you know the procedure by now …when a particle is constraint to move on a circle, what are the constraint forces

There is no way that F has anything to do with motion around the circle you have drawn.And this is the reason why it is harder to apply a force like on the picture to a circle of smaller radius and that is because there will be a component of the centripetal force that is opposite to the applied force F on the picture and that’s why torque gets smaller with r.
the forces on the string are the tension force witch acts on the pivot where you binded the string and the same acts also on your hand but i dont see what this has anything to do witch my questionLooking at your diagram I think I understand your question.
Unfortunately, taking your posts in this thread and your previous one, you seem to have a basic misunderstanding about circular motion.

None of this is meant as a personal criticism; I really am trying to help.
You did not bother to answer my previous question. All my questions are designed to help and further understanding.
Have a look at this recent thread, where I like to think the OP went away with a better understanding and achieved something for himself.

Now just answer this simple question.
If you take a string and pull it out taught so it is under tension, what are the forces acting in the string and on the string?
Can you draw a simple diagram?
This doesn't make sense. Is the force acting on the string or the pivot? I actually asked about the string.the forces on the string are the tension force witch acts on the pivot
