I What force is needed to collapse this spring-loaded pair of arms?

AI Thread Summary
To collapse the spring-loaded arms, a specific force must be applied to counteract the spring tension. The system functions similarly to an awning, where the arms extend when opened and retract when closed due to the spring's force. Understanding the forces acting on both the arms and springs is crucial for determining the necessary applied force. The discussion includes a schema to clarify the mechanics involved. The goal is to effectively return the arms to their closed position using the spring's properties.

Hello .
The goal is to look for what force F I need to apply in order to return the arms to the closed position. Attached is a schema in the hope that my purpose will be understood
I want to know what forces are acting on the system of the arms as well as the springs
Many thanks in advance

Can you say what the function of the two hinged arms is? What is this used for?
 
Arm release: The system release is like an awning to the sun that has arms.
When the awning opens the arm opens and because the spring is stretched the arm tends to open. And when I want to return the awning to the closing position with the help of the spring force the arms are returned to their original place
I added again the agreement in which there is the spring in all three modes
Thank you very much for your reference. Daniel

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...
