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 '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
