Statics : Force on Equilibrium Problem

  1. May 27, 2010 #1
    1. The problem statement, all variables and given/known data

    Three (3) Identical Cylinders each weighing 80.2 were tied together by a wire and was placed on a smooth horizontal surface as shown determine minimum tension acting on the wire.

    hint: the answer 20 < Tension < 30

    Figure below:

    2. Relevant equations

    [tex]\sum[/tex]Mo = 0
    [tex]\sum[/tex]Fx = 0
    [tex]\sum[/tex]Fy = 0

    3. The attempt at a solution

    First I noticed that the 3 cylinders are were tied together so the distance from the Center of AB , AC , CB are equal and it forms an equilateral triangle so it forms an angle of 60degree
    and after this i dont know how to do my FBD or what principle will i use to find the minimum tension acting on the system.
    and my professor said that 20 < minimum tension < 30
    help guys this problem can be the problem on my quiz later :(

    What you need is the FBD. Try something and post it here. If you don't show your attempt, nobody will try to help.
    You are on the right track with the angles. Now do the FBD
