- Homework Statement
- A 6.00 m, 0.732 kg wire is used to support two uniform 235 N posts of equal length (the figure (Figure 1)). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 5th overtone.

- Relevant Equations
- \sum tau = 0

Hello,

Can someone help me out with this one. I solved the exercise but didn't get the right answer so I went searching on internet for solutions. It seems something was wrong with my force-diagram. In my force diagram I had another force included excerted by the wire on the post, since the wire has weight that must be carried by the posts there has to be a reaction force hasn't it? Although in the solutions I added to the post the only force excerted by the wire on the post is horizontal tension force that cannot cancel out the weight of the wire.

Thank you in advance!
