Two bars \( A \) and \( B \) are stuck using an adhesive. The contact surface of the bars make an angle \( \theta \) with the length. Area of cross section of each bar is \( S_{0} \). It is known that the adhesive yields if normal stress at the contact surface exceeds \( \sigma_{0} \). Find the maximum pulling force \( F \) that can be applied without detaching the bars.
(a) \( \frac{\sigma_{o} S_{o}}{\sin ^{2} \theta} \)
(b) \( \frac{\sigma_{o}}{S_{0} \sin ^{2} \theta} \)
(c) \( \frac{\sigma_{o} S_{0}}{2 \sin ^{2} \theta} \)
(d) \( \frac{\sigma_{0}}{2 S_{0} \sin ^{2} \theta} \)
