Calculating the Centripetal force of a trebuchet

AI Thread Summary
Calculating the centripetal force of a trebuchet involves understanding the net force on the object and its radial component along the trebuchet's arm. The discussion clarifies that the force in question may not be centripetal until the projectile is released. Participants suggest reviewing foundational concepts and consulting educational resources for better understanding. The original poster expresses confusion about the calculation process and seeks further guidance. Overall, the conversation emphasizes the importance of grasping the underlying physics principles involved in the mechanics of a trebuchet.

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 centripital, 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.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
