(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Due to a jaw injury, a patient must wear a strap (see the figure) that produces a net upward force of 5.00 N on his chin. The tension is the same throughout the strap.

To what tension must the strap be adjusted to provide the necessary upward force?

2. Relevant equations

[tex]\Sigma[/tex]F=O??

3. The attempt at a solution

I already know the answer its 3.15 N I cant figure out how to get it though. I'm assuming its a equilibrium problem and if it needs an upward force of 5N the force due to gravity would also be 5, right?
