Pulley system

  1. Oct 27, 2014 #1
    1. The problem statement, all variables and given/known data
    Three equal masses are hung from a pulley(2 on one side, 1 on the other). Find the acceleration of the system and the tension between: a) the 2 sides of the pulley and b) between the 2 masses on the same side

    2. Relevant equations


    3. The attempt at a solution
    Got a= g/3, for a) T= 13.3m N and not 100% sure about b)

    Good.

    What do you think? Apply Newton's 2nd law to one of those masses.

    Is it T= 2g/3 N?

    Yes, but you left out the mass.
