Thks guys. It really helped. I think I've made some miscalculations. But now i get it. :D

Homework Statement As shown in attachment a steel cable is stretched between two poles. In 20°C temperature the cable remains horizontal (the length of the cable 10m). At a higher temperature θ°C the cable bends like in attachment. The lamp hanging from the mid-point could be...

Finally I got it figured. I had overlooked the original problem statement that it was a meter ruler hanging from the string. So l = 1m. And I felt kinda stupid when i found that. But huge thanks goes to everyone who had to waste their valueble time for my stupidity. :D

Okay I think I've made some progress Writing for the linear forces I got this: 2W = mu * Tcos(10) + Tsin(10) ------> 1 So W/T = -0.4 Then I took torques at the wall-end : WL/2 + Wx = LTSin(10) -------> 2 And substituted W = -0.4T in the second equation and thus L/x = 1.18 But I have no...

Sure it still stands. So can you please clarify it a little bit more on finding the value of 'x'. (It would immensely help if you can show me how to build the equations necessary). I'm hoping that I'm not overly bugging you.

oops.. my bad here's the attachment

Homework Statement A pole is suspended horizontally between a wall and an attached string.(See the attachment). An object(W) is hanging from the pole at a distance of x from the wall. Find the value of x that preserves the equilibrium. 1) the angle between the pole and the...
