Strings and Atwood Machines

  1. May 31, 2016 #1
    1. The problem statement, all variables and given/known data
    When talking about an Atwood machine, a student states:
    Is the student correct or incorrect? Why?

    2. Relevant equations
    Tension = mg + ma

    3. The attempt at a solution
    This is how it is making sense in my mind, but correct me if I'm wrong.
    I am thinking that the student is incorrect, because the tension force on the string holds objects together. The weight of one block isn't transmitted from one block to another, but the forces on the blocks are a result of one another through the string.

    I think I could argue either way... but it reads like you've said the same thing as "the student", but in different words.
