1. Collars A & B are connected by a 525-mm long wire and can slide freely on frictionless rods. If force P= (341 N)j is applied to collar A determine the tension of the wire when y=155mm and the magnitude of force Q(which is along the z axis) to maintain equilibrium
2. Homework Equations
[tex]\Sigma[/tex]F=0
[tex]\overline{v}[/tex]=[tex]\sqrt{vx^2+vy^2+vz^2}[/tex]
3. The Attempt at a Solution
I was given y was 155mm and x=200mm and found the z value of the wire to be 460mm. I then created a unit vector for the wire and came up with these equilibrium formulas:
[tex]\Sigma[/tex]Fx=[tex]200/525[/tex]Tab=0 (Something is wrong here)
[tex]\Sigma[/tex]Fy=[tex]-155/525[/tex]Tab=-341N
[tex]\Sigma[/tex]Fz=Q+[tex]460/525[/tex]Tab=0
Now I'm stuck...can anyone lead me in the right direction?
