Ah okay, you might be right here. We both use different approaches. While I use physical coordinates (Cartesian coordinates) while you describe vector loops. I didn't think about it because last few problems I dealt with this approach due to simplicity and other aspects as springs etc.. The...

Thank you for the reply. I'm aware of this; I just think we use a different way to apply the constraints (in terms of the number of coordinates - degrees of freedom). Well, that shouldn't change anything since yours works with vectors, so for example, the magnitude of the BA vector will...

Or do I just create two additional angles on each side but make it as Beta_v with these angles equals 180 degrees?

Well yeah, the CM of the triangle will be calculated based on the angle and the lengths. It's as simple as the equation taught in elementary school, instead of actual numbers there will be the variables. I struggle a bit with the angle Beta_v as I try to create the constraints equation I need to...

Not really, but after thinking about it and reconsidering the other problems we did in class, it kind of makes more sense. Considering the system, it also seems logical that if I were to imagine a motor down there, I would aim for a smaller reaction force as well. Also, it sounds harder...

Thanks for the answer. It's basically what you say and what I stated in the beginning. First, I need to define all the coordinates, particularly the mass centers, as they will be used in the system's kinetic energy. Since the green segment is treated as one area, I’ll also need to derive the...

Edit: The max RA might be more likely the reaction force at A.

TL;DR Summary: Applied mechanics, mechanics, optimization, dynamics, kinematics Hi, I'm trying to finish this assignment and I'm not completely sure how to proceed. Should I first create the constraint equations, then the kinematics to get the derivatives for velocities and accelerations...
