Calculating the Centripetal force of a trebuchet

[James626]

I need help with calculating the centripetal force of a trebuchet. I have tried to derive an equation from a free body diagram, but I am sure that I'm doing something wrong.
Does anyone know how to calculate the centripetal force?

Welcome to the PF.

The force is not centripetal, is it? BTW, is this for a school project?

You find the net force on the object and then find its component along the trebuchet's arm (radial direction). Done.

Yes, this is for a lab that I am doing. I have also had doubts about the force not being centripetal. But I think that technically it is until the object is released.

How do I do that? Sorry I literally have no idea what to do.

In that case, ask your teacher after class or go back through your book because you are missing some very important points.
