Mechanics help please!
Hi, can anyone help me with the following mechanics question:
http://tinypic.com/f1iogj.jpg"
I've attempted this question but I'm stuck on how i can prove that θ = 45°
I've constructed a diagram but I haven't scanned it but what I've got so far is from the diagram at point C, by resolving horizontally i find that the tensions, say T1 and T2 are equal to each other and I label this as T.
Resolving vertically I get 2T cos θ - w = 0
for the bead on the far left, by resolving horizontally I got:
F1 - T1 sin θ = 0 (F1 being the force acting towards the left)
vertically I get: N1 - T1 cos θ - w = 0
For the bead on the far right, by resolving horizontally I get:
F2 - t2 sin θ = 0
vertically:
N2 - T2 cos θ = 0
And this is where I'm stuck...I don't know where to go from here. Am I on the rght track? Can anyone help? Thanks! Sorry again that I haven't provided my diagram
