Okay using you notation I do get to cos theta = x/(L/2) = 2x/L
But I can't figure out where the 2 came from in 2T cos(theta) = mg, are we using cos(theta) = adjacent side/ hypotenuse i.e cos(theta) = mg/ tension?
I understand how you got from there to T=mg*L/(4*x) however.
Thanks for the...
This question came up in my physics holiday homework and I can't seem to get the correct answer :(
