A simple system of two masses and two pulleys

Click For Summary

Homework Help Overview

The discussion revolves around a system involving two masses and two pulleys, with a focus on determining the expression for the acceleration of the two masses. The original poster expresses confusion over differing answers obtained in previous attempts.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster shares their attempts but indicates inconsistency in their results. Participants inquire about the details of these attempts to provide guidance. There is a mention of a relationship between the accelerations of the two masses, with some questioning the correctness of this relationship.

Discussion Status

The discussion is ongoing, with participants seeking more information about the original poster's attempts. A suggestion has been made regarding the constraint imposed by the constant length of the rope attached to one of the masses, which may influence the relationship between the accelerations.

Contextual Notes

There is an emphasis on the need for detailed attempts to facilitate assistance, and the original poster is encouraged to clarify their reasoning and assumptions regarding the system.

hey there,

I am confusing what is the right answer to this system of mass, I solved it a couple of time and I got different answers. can you help me with that?
I need to find the expression of the acceleration of the 2 masses.

thanks a lot,Adam.

on the left middle; if the system was stretch all the way. it will be easier to find the length equation, thanks a lot/

I see you somehow got that a1=a2. That is incorrect.

Consider that the rope attached to M2 is of constant length. That places a constraint on the relationship between a1 and a2.
