A rigid rod is pivoted at its right end. Three forces of identical magnitude but different direc- tions are applied at the positions 1,2 , and 3 as shown, where $$\(F_{1}\)$$ and $$\(F_{3}\)$$ make $$\(45^{\circ}\)$$ angles with the vertical. Which of the following correctly ranks the torques $$\(\tau_{1}, \tau_{2}\)$$, and $$\(\tau_{3}\)$$ provided by the forces $$\(F_{1}, F_{2}\)$$, and $$\(F_{3}\)$$ ?
A.
\(\tau_{1}> \tau_{2}> \tau_{3}\)
B.
\(\tau_{3}> \tau_{2}> \tau_{1}\)
C.
\(\tau_{2}> \tau_{1}> \tau_{3}\)
D.
\(\tau_{2}> \tau_{1}=\tau_{3}\)
