The book and I aren't getting along tonight. Maybe you can help.(adsbygoogle = window.adsbygoogle || []).push({});

A rope of length L has a tension T. Someone pushes on the rope with a force F at its midpoint and deflects the rope by a distance d. What is T is terms of L,d and F.

This is so simple I won't even explain my work.

2Tsinθ=F

sinθ=d/(L/2)=2d/L (approx)

so

[tex]T=\frac{FL}{4d}[/tex]

Right?

The prob. in the book had numbers, but in the end I was off by a factor of 2.
