Homework Equations
The Attempt at a Solution
So I get that
ƩFy = 0 = F(rod)y - F(weight)
ƩFx = 0 = F(rod)x - F(spring)
F(spring) = 200N * (1.5m + d)
d being the unknown distance that the rod has moved by.
So I get
F(rod) = 60N / sinθ
F(rod) = (200N * (1.5m + d)) / cosθ
Which leaves me with 3 unknowns.
d & θ & F(rod)
But only 2 equations
So I have no idea where to go from here
