Homework Statement
A weight of 10 N is hanging from the top of a three-legged support. The legs are attached to the horizontal floor and form equal angles with each other. Find the forces in the legs, if they form an angle of 30 degrees with the rope.
Homework Equations
\sumFx=0...
I get that the sum of all the forces is zero. However I still have two unknown forces, one along the rope and the electromagnetic force. Even knowing the sum of all three doesn't help. What am I missing?
This is probably really obvious but I have a hard time with vectors and really don't know what it's supposed to look like..I'm not even sure if to draw the grav. force vectors starting from the ends of the ropes or straight down from the centers of the bullets.
