Circular Motion - Triangular Frame

Click For Summary
The discussion revolves around solving a problem involving a triangular frame in circular motion with an accelerating frame. A pseudo-force of 3mg/2 is applied to points B and C in the leftward direction due to the frame's acceleration. The Center of Mass (CoM) is identified as lying at the midpoint between B and C, with a known distance to point A. Participants express confusion about the application of forces and the conditions under which the masses complete a circular motion. The conversation touches on concepts from Lagrangian mechanics, work and energy, circular motion, and kinematics.

The Attempt at a Solution


I'm going to post all that I figured out or tried. Most of it is really just pieces of information that I don't know how to put together.

The frame is accelerating, so I have to apply a pseudo-force of \frac{3mg}{2} on B and C in the leftward direction.
The Center of Mass of the system lies on the midpoint on B and C. I know the distance between the CoM and A.

I tried energy conservation, taking zero potential at BC. That didn't help either.

i can't see your question
is it a pic?
 
If i am guessing right, frame is acc. along +X axis so you should apply pseudo force in -X

but i can't understand which is going where and masses should complete a circle in frame of A? ... it will if there is no gravity... and is the figure parallel to ground or what>?
 
are you familiar with Lagrangian mechanics
 
not exactyl that i have studied somthing like that but i have studied topics work&energy, circular motion, kinematics, momentum and stuff
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
