Homework Help: Vectors - Force Table

  1. Oct 5, 2008 #1
    1. The problem statement, all variables and given/known data
    1.Show using a force triangle that the vector addition of the 3 forces is zero.
    2. Calculate the X and Y component of forces and show that for each set of data:

    Trial A: Mass(g) Direction (°)
    F1 (Pulley#1): 50g 200°
    F2 (Pulley#2): 95g 0°
    F3 (Pulley#3): 50g 160°

    2. Relevant equations
    I think you use Newton's Second Law?

    3. The attempt at a solution

    1) Calculate the forces of each pulley
    ΣF= F1+F2+F3=0
    *How do I calculate the force of the pulley?


    * will edit the rest in later as I figure it out :P
