hey @amistre64 think you can help at all with this one?

amistre64 · Answer

tensions eh ...

amistre64 · Answer

if it is in a state of rest ... the all the forces must cancel out

amistre64 · Answer

OR are they assuming that the magnitude of each vector is the tension to find?  its a bit vague to me

amistre64 · Answer

maybe i should read the question lol

johnweldon1993 · Answer

^ that is what I was assuming...the magnitudes would be the tension. And yes equilibrium...

I've never worked on 3D tension problems before so this is a curveball for me

amistre64 · Answer

its just an extra information to keep track of ... find that angle of each vector between the  .. loos like a zx plane for confusion
