# Vectors - Force Table

1. Oct 5, 2008

### Masq

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:
ΣFx=0
ΣFy=0

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
F1=
F2=
F3=
ΣF= F1+F2+F3=0
*How do I calculate the force of the pulley?

2)

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