Circular Motion - Triangular Frame

Click For Summary

Homework Help Overview

The discussion revolves around a problem related to circular motion involving a triangular frame that is accelerating. The original poster attempts to analyze the forces acting on the system, particularly focusing on the application of pseudo-forces due to the acceleration of the frame.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of pseudo-forces and the position of the center of mass. There are attempts to apply energy conservation principles, though the original poster expresses uncertainty about how to integrate the information. Questions arise regarding the orientation of the frame and the conditions under which the masses would complete a circular motion.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem setup and exploring various interpretations of the forces involved. Some guidance has been offered regarding the direction of the pseudo-force, but there is no explicit consensus on the overall approach or solution.

Contextual Notes

There is a mention of the frame's acceleration and the need to consider gravitational effects, as well as the original poster's background in related physics topics, which may influence their understanding of the problem.

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 [tex]\frac{3mg}{2}[/tex] 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.
 
Physics news on Phys.org
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
