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

determine the value of Beta for which the tension in cable B is as small as possible, then find the corresponding tension. Given Alpha = 5 degrees and the weight of the object is 12kN

This is an image of it http://imageshack.us/photo/my-images/801/unledgsn.png/

2. Relevant equations

Fy=0 Fx=0 (at equilibrium)

3. The attempt at a solution

Fx= -T_{A}sin5 + T_{B}cos(Beta)

Fy=T_{A}cos5 - T_{B}sin(Beta) - 12

from Fx i get T_{A}= (T_{B}cos(Beta))/Sin5

and i plug it into Fy to get 12=T_{B}(11.4cos(Beta)-sin(Beta))

but this doesnt answer my first question of what is the angle, only helps with part 2 of the question..
