Homework Equations
F = uR
The Attempt at a Solution
I don't understand the followings:
For equilibrium at A, the equation should be F1 = T sin [tex]\theta[/tex]. Am I right?
While for the one at B, the equation should be F2 = T sin [tex]\theta[/tex]. Am I right?
In addition, how can I get cos [tex]\theta[/tex] = (au2 + 1)-0.5 at the last answer?
Thank you very much!
